How To Measure | Close it Using a measuring tape
Here's a little refresher on how to use a measure tape. First, let's talk about the increments. We'll assume that you're using the English or Imperial system of feet and inches. Extend your tape measure several inches and find the large 1 and 2. On most English measuring tape, the smallest increment is 1/16 of an inch. This means that there are 16 equally spaced marks between 1 and 2 inches on the tape. When measuring, count how many of these marks you are beyond the nearest inch. If your piece measures 7 inches and other 8 marks, that is 8/16 (1/2) for a total of 7-1/2".Let's say you were taking your second measurement (see below) and this time you counted 9 marks past the 7 inch mark. That means your piece is actually 7-9/16" long.
The clip on the end of my measuring tape slides back and forth. Is it broken?
No! The sliding clip on the end of the tape is designed for two different types of measurements. When you take an outside measurement (where you hand the clip of the tape over an edge), the clip slides out a little to account for the thickness. When you take an inside measurement (push the clip up against a surface), the clip slides in, again accounting for its thickness. The measuring tape self-adjusts so, either way, you get an accurate measurement.
Measure Twice, Cut Once
Once we cut a stock size piece, we can't ever sell it as full size piece again. So, PLEASE MEASURE CAREFULLY, and DOUBLE CHECK YOUR MEASUREMENTS BEFORE YOU ORDER. The old adage is espcially true here: measure twice, cut once. WE do it before we cut your piece, and YOU should do it before you order.

ACRCLE1 - Overview
Abrasion resistant Acrylic sheet (AR1) is produced by applying a very hard, highly crosslinked polysilicate (a silicon polymer or polysiloxane) coating to an Acrylic substrate. This coating provides the sheet with a surface that has 45 times the abrasion resistance of uncoated Acrylic, making it an attractive material for applications requiring the safety, optical and aesthetic qualities of Acrylic along with a highly abrasion-resistant surface. Ideal for menu boards, cosmetic displays and map overlays
Acrylics have outstanding resistance to long-term exposure to sunlight and weathering. Acrylic has excellent optical properties and is more resistant to impact than glass. In addition, acrylic has low water absorption, good electrical resistivity, and fair tensile strength. Applications are infinite, including art installations, outdoor signs, glazing, aircraft canopies, skylights, automotive taillights, dials, buttons, lighting applications, knobs, and machine covers.

Cast Acrylic vs. Extruded Acrylic:
Acrylic is produced in two basic variations, cast and extruded. Casting and extruding acrylic produce slightly different properties. Cast acrylic is more difficult to bend and shape versus extruded. In heat bending and thermoforming, extruded acrylic may behave differently depending on the bending direction relative to the extrusion direction. This is not an issue with cast acrylic. When colored cast acrylic is heated for thermoforming or heat bending, the color may change. Matte-colored surfaces can become clear and clear surfaces can become matte or opaque. In addition, the shade of color may change. Laser engraving should only be done on cast acrylic to produce a clear engraved image. In laser cutting, extruded acrylic will have a rougher edge, whereas cast is generally smooth. Cast is more difficult to flame polish versus extruded. Extruded acrylic tends to be more consistent in sheet thickness, while cast can vary as much as +/- 15% in thinner sizes. Cast acrylic is more resistant to the same solvents, as well more resistant to scratching versus extruded.
Acrylic applications are infinitely broad. Here are a few common examples:
• Glass Substitute: aquariums, viewing ports for submersables,
automobile light lenses, hockey rink guards, riot protection,
bullet-resistant glass applications (i.e. banks, gas stations,
vehicles transporting valuables)
• Medical: intraocular lenses, dentures, dental filling, liquid
rerouting
• Aesthetic: furniture, layered painting, photo framing,
architectural installations, signage
• Light Redirection: even lighting dispersion panels,
greenhouses, decorative lighting instalations, light shelves
