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.

Compatible Polycarbonate Disinfectants:

• sBioMed Steriplex SD
• Safetec Surface Wipes
• Contec Healthcare Perodox RTU
• Contec Healthcare PS-911 EB Prostat Sterile Wipes

Compatible Acrylic Disinfectants:

• Pharmacy Grade Hydrogen Peroxide
• Household Bleach
• Isopropyl Alcohol (Water Diluted to 30% Strength)

Overview Specs & Uses Reviews Inquiry
PVCWCF SH - Overview

LAM CRP-1 flame retardant sheet is an FM4910 and UL94 V-0 rated material that uses a PVC based formula to create a high performance, fire retardant material perfect for the semiconductor industry. LAM CRP-1 plastic resists temperatures much higher than that of standard PVC grades and is impact modified for increased durability against impact forces and extreme temperatures. Its temperature resistance exceeds that of standard PVC. LAM CRP-1 also works well for wet bench applications (like cabinetry and enclosures) and has a high surface gloss for an attractive look in cleanroom applications. LAM CRP-1 can more easily be welded versus PVC-C: in comparative welding trials, CRP-1 has been shown to weld quicker and with more ease versus PVC-C and other FM 4910 listed PVC grades.

LAM CRP-1 sheet has been found exceptionally useful for the following applications:

  • Semiconductor processing equipment
  • Industrial process rinse, water recycling systems, and water transfer interfaces
  • Clean room enclosures and cabinets
  • Dry tool enclosures
  • Electrical cabinets

  • FM4910 and UL94 V-0 compliant
  • Impact modified for high durability
  • Consistent and attractive surface gloss
  • High resistance to alkalines and acids
  • Works well in contact with ultra-pure water systems in wet bench applications
  • PVDF weldable (with JSR hybrid welding rod)
