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).

Originally known by the brand name Kel-F®, PCTFE is now also known by the brand name Neoflon®. A unique fluoropolymer with both chlorine and fluorine in its composition, PCTFE has high compressive strength and stability over a wide range of temperatures. It is a rigid material that exhibits good dimensional stability and low deformation under load. This material has near zero moisture absorption and will retain its dimensional stability in humid or marine environments. PCTFE is radiation resistant and non-flammable. It will continue to perform well in extreme temperatures ranging from -400°F to 284°F. PCTFE meets the following classifications: - ASTM D 1430-89 Type 1, Grade 2
- ASTM D 1430-95 Type 1, Grade 3
- ASTM D 1430-17 Group 1, Class 1, Grade 3
- ASTM D 7211-18 (section 8.8)
- ASTM D 7194-19 (section 10.4)
- FDA Compliance per 21 CFR177.1380
- USP Class VI compliant
- Good dimensional stability and rigidity
- Low deformation under load
- Near zero moisture absorption
- Non-flammable
- Resistant to radiation
- Excellent chemical resistance
- Good corrosion resistance
- Low outgassing
