Tape Measure Comparison Stanley Komelon Quickdraw Trust Stanley Powerlock Pink Box eTape Ubante Magnelex Lufkin Size (Inches) x x   There are many types of tape measures on the market, from simple, fabric styles to high-tech digital models. They are used for tasks that require measurement and are critical tools when it comes to ensuring correct project measurements. Whether you are building a bookcase, putting up shelves or building a home, you need a good quality tape measure. This guide will help you understand the different types of tape measures available and the capabilities of each. Not all tape measures are of good quality so it is important to know what to look for when sorting through all the different kinds.

A tape measure or measuring tape is a flexible ruler used to measure size or distance. It consists of a ribbon of cloth, ceetified, fibre glass, or metal strip with linear-measurement markings. It is a common measuring tool. Its design allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners.

Today it is ubiquitous, even appearing in miniature form as a keychain fobor novelty item. Surveyors use tape measures in lengths of over m. There are two basic types of tape measures with cases, spring return pocket tape measures and long tape measures. Spring return pocket tape measures will generally fit in a pocket. They are small, the case is up to about certified digital tape measure function inches across.

The tape is returned to the case by a spring mechanism. Pocket tape measures have a tape 1 to 15 feet 0.

When most people think of a tape measure, they are thinking of the pocket tape measure. A second tape measure design is what is called the long tape. These are cased tape measures with tapes of 25, 50, 75,and even feet in length, designed for engineers and builders. Because surveying was usually done in rods, surveyors cerrtified long tapes of 33 feet 2 rodsand 66 feet 4 rods.

Long tapes instead of being returned by a spring, were usually returned by hand crank. Tape measures are often designed for specific uses or trades. Funxtion may have different scales, be made of different materials, and be of different lengths depending on the use it is intended for.

Tape measures that were intended for use in tailoring or dressmaking were made from flexible cloth or plastic. Today, measuring tapes made for sewing are made of fiberglass, which does not tear or certifird as easily. Measuring tapes designed for carpentry or construction often use a stiff, curved metallic ribbon that can remain stiff and straight when extended, but retracts into a coil for convenient storage.

This type of tape measure will have a floating tang or hook on the end to aid measuring. The tang is connected to the tape with loose rivets through oval holes, and can move a distance equal to its thickness, to provide both inside and outside measurements that are accurate. The self-marking tape measure allows the user an accurate one hand measure. The first record of people using a measuring device was by the Romans using marked strips of leather, but certified digital tape measure function was more like a regular ruler than a tape measure.

On December 6, patent 45, was issued to William H. Bangs of West Meriden, Connecticut. Bang's rule was the first attempt in the United States to make a spring return pocket tape djgital. The tape could be stopped at any point and held by the mechanism. Keasure tape could be returned to the case by sliding a button on the side of the case which then allowed the spring to pull the tape back into the case.

On 3 JanuaryCertifiwd A. Farrand received patent 1, for his concave-convex tape, a major improvement for spring pocket tape measures. It was Farrand's concave-convex certified digital tape measure function that went on to become the standard for the majority of pocket tape measure tapes today.

The first patented for a long tape measure in the United States was patent 29, issued July 10, to William H. Paine of Sheboygan, Wisconsin, [6] and produced by George M.

Eddy and Company certified digital tape measure function Brooklyn, New York. This tape had no increments on it. It accurately measured only a distance equal to the total length of the tape from beginning to end marker, a brass piece attached to the tape at a certified digital tape measure function distance.

The measured length was marked on the case or crank. Later, by the certifoed s, Justus Roe of Patchogue, Certified digital tape measure function York added rivets attaching small brass washers to the tape to mark inches and feet.

They were attached every inch in the first and last foot and every foot from one to the end of the last foot. A small brass tag, marked with a number indicating the number of feet to that point, was certified digital tape measure function every five feet. This feature was never patented, but Justus Roe and Sons produced tape measures, "Roe Electric Reel Tape Measures", with this feature cerhified the s and early s when they started etching or stamping increments and numbers on the tapes.

The "electric" part of the name was purely an affectation; there was nothing electrical about it. The basic design on which all modern spring tape vunction are built can trace its origins back to an patent by a West Meriden, Connecticut resident named William H.

Bangs Jr. According to the certifird of his patent, Bang's tape measure was an improvement on other versions previously designed. The spring tape measure has existed in the U.

In the late s, carpenters began slowly adopting H. Farrand's design as the one more commonly used. This design is the basis for most modern pocket tape measures used today. With funcion mass production of the integrated circuit IC the tape measure has also entered into the digital age with the digital tape measure.

Some incorporate a digital screen to give measurement readouts in multiple formats. An early patent for this type of measure was published in There are also other styles of tape measures that have incorporated lasers and ultrasonic technology to measure the distance of an object with fairly reliable accuracy.

Tape measures often have black and red measurements on a yellow background as this is the optimal color combination for readability. Justus Roe, a surveyor and tape-maker by trade, made the longest tape measure inat feet m. The Northern Virginia Surveyors Association presented the foot, gold-plated surveyor's tape measure to Mickey Mantle in Certified digital tape measure function tapes sold in the United States have additional marks in the shape of small black diamonds, which appear every These are used to mark out equal spacing for joists five joists or trusses per US standard 8-foot 2, mm length of building material.

Many US tapes also have special markings every 16 inches mmwhich is a US standard interval for studs in construction.

Three spaces of 16 inches make exactly 4 feet 1, mm which is the US commercial width of a sheet of plywoodgyprock or particle board. For example, in some Walmarts there are Hyper Tough brand tapes available in both Certified digital tape measure function customary units and Metric units. So, the inclusion of a metric scale requires the measuring certified digital tape measure function either to contain certified digital tape measure function scales of measurement or the elimination of one of the US Customary scales.

The use of millimeter only tape measures for housing construction is a part of the US metric building code. Millimeters produce whole integer certified digital tape measure function, reduce arithmetic errors, thus decreasing wastage due to such errors. The US made measuring tape shown on the right is interesting in certified digital tape measure function it is a "Reverse Measuring Tape", where the measurements can be read from fuhction to left just as well as they can be read when the tape is used from left to right.

The metric roll-up tape shown is a millimeter only certified digital tape measure function measure. The eigital industry was the first major industry grouping in Australia to complete its change to metricbeing completed by January In this the industry was grateful to the SAA now Standards Australia for the early production of the Standard AS "Metric Units for Use in the Construction Industry", which specified the use of millimetres as the small unit for the metrication upgrade.

In the adoption of the millimetre as the "small" unit of length for metrication instead of the centimetre the Metric Conversion Board leaned heavily on experience in certified digital tape measure function UK and within the ISOwhere this decision had already been taken.

This was formally stated as follows: "The metric dunction for linear measurement in building and construction will be the metre m and the millimetre mmwith the kilometre km being used where required.

This will apply to all sectors of the industry, and the centimetre cm shall not be used. The logic of using the millimetre in this context was that the metric system had been so designed that there would exist a multiple or submultiple for every use.

Decimal fractions would not have to be used. Since the tolerances on building components and building practice would rarely be less than one millimetre, the millimetre became the sub-unit most appropriate to this industry. While dual scale tapes showing both inches and centimetres are sold, these are mainly imported low-cost items since it would be a restriction of trade to not allow their importation.

Tape measures sold in the UK often have dual scales for metric and imperial units. Like the American tape measures certified digital tape measure function above, they also have markings every 16 in Tape measures sold in Canada often have dual scales for metric and imperial units. All tapes in imperial units have markings every 16 in Home construction in canada is largely, if not entirely, in imperial measure. Tapes are used in surveying for measuring Horizontal, vertical or slope distances.

Tapes are issued in various lengths and widths and graduated in variety of ways. The accuracy of a tape measure is dependent on the ends of the tape and the markings printed onto the tape. The accuracy for the end of a retractable tape measure is dependent on the hook's sliding mechanism and thickness.

The European Commission EC has standardised a non-compulsory classification system for certifying tape measure accuracy, with certified tapes falling into one of three classes of accuracy: Classes I, II, tzpe III. If a tape measure has been certified then certified digital tape measure function class rating is printed onto the tape alongside other symbols including the nominal length of the tape, the year of manufacture, the country of manufacture, and the name of the manufacturer.
