Checking Custom Mat Dimensions Before Site Installation
Custom mat deliveries should be checked against the signed manufacturing drawing before installation. Comparing only the mat's overall appearance can miss a reversed orientation, wrong section division or dimensional discrepancy.

Selection considerations
Use the approved location and drawing revision to identify the package. Check the supplied mat and frame dimensions using the agreed measurement method. Distinguish the mat's dimensions from the recess dimensions so a required interface is not misreported as a defect.
Review panel identity, insert arrangement and accessories with the packing list. Keep unmatched items separate and ask the supplier to resolve them. Do not force, cut or modify a custom assembly merely because the delivered package resembles the intended entrance.
Record acceptance or unresolved items before issue to the installer. If the recess has changed since measurement, identify the change separately from the delivery check. Keep photographs and the signed drawing with the record so the discussion can focus on the actual discrepancy.

Common question
Is fitting the mat into the recess the best first delivery check?
No. Identify and measure the assembly against the approved manufacturing information before attempting installation.
