How To Measure and Cut-To-Size Policy [X]

Cut-To-Size Items are Non-Returnable!

As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade. Please review our full return and shipping policy here.

Measure Twice, Cut Once

Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.

How to Use a Measuring Tape

Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.

Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.

Features of a Measuring Tape: Sliding End Hook

The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).

Sanitizing Acrylic and Polycarbonate Sheet [X]

Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.

Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.

Precision Board High Density Urethane (PBLT) is a rigid polyurethane foam board and sign board made specifically for applications of up to 200?F continuous exposure. Due to its closed cell structure, HDU Precision Board produces less dust and more chips when cut or machined and doesn't absorb moisture. It can handle higher feed rates than other materials like wood or epoxy substrates. HDU Precision Board is dimensionally stable, with a knot-free uniform surface that will not rot, crack, or peel when exposed to outdoor environments. It lasts up to 10 times longer than wood and is commonly used as a substitute for outdoor wooden signage. HDU Precision Board is a versatile material - in addition to dimensional signage, it is used for master model making, tool proofing, prototyping, and carvings.

An environmentally friendly material, HDU Precision Board is made with eco-friendly urethane and is completely inert. It is non-toxic and contains no VOC's or carcinogens. Interstate Plastics offers HDU Precision Board in 6 standard densities, but more are available upon request. PBLT-40's density is 40 lbs./ft.3.
