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 OnceSince 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 TapeExtend 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 HookThe 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).

American-made & ready to ship. Please specify the width of your existing barrier (2" - 3") and whether the barrier is round or square in the comments section during checkout. School partition extensions attach to existing dividers and are a great way to create taller physical barriers in the classroom without buying a set of larger barriers. These partition extensions are clear and will not disrupt classroom lighting or visibility. At 3/16" thick, school partition extensions are sturdy and easily cleaned. All partition extensions include a 3/4" thick intersecting partition cap which holds intersecting extensions together. Not seeing the size you need listed above?
