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).

Hydex® 4101 PBT (PolyButylene Terephthalate) is a food grade polyester thermoplastic with excellent chemical and impact resistances. With roughly 20% more impact resistance than PET-P, parts machined from Hydex® 4101 are less likely to break during operation and can withstand high impacts without breaking. As a food grade plastic, it is approved for direct contact with food and is a natural fit for food processing equipment parts where impact and wear resistance over a prolonged period of time is a concern.

Hydex 4101®'s superb resistance to chemicals commonly used in cleaning agents allow for more frequent cleaning without degrading its mechanical properties. It has a low moisture absorption rate, only absorbing up to 15 times less than nylon.

Hydex® 4101 PBT is easier to machine than PET-P and is an ideal material for parts in food processing or engineering equipment. It also has applications in the pharmaceutical and automotive industries.


  • Resists cleaning solutions - excellent chemical resistance
  • Good wear resistance
  • Good machinability
  • Resistant to impacts
  • Low moisture absorption - 15 times less than nylon


Handling: Cut materials may have sharp edges. We recommend wearing protective gloves when unpacking and handling this material to ensure safety.

Suitability: We take pride in the quality of our materials as they leave our facility. However, because every project is unique, we cannot account for how materials are modified, stored, or used after delivery. Please perform the necessary tests to ensure this material is right for your specific application and end-use conditions.
