WBT Form
WBT offers an alternative to expensive and heavy metallic inserts. WBTform is a polymer insert, UL 94V-0 flame rated and RoHS compliant.
WBT form is available in lengths up to 30 feet, and can simply be unrolled into the tray. Want an insert that covers both the bottom and sides of the tray? WBTform can be scored so that it’s a custom fit, providing a solid surface for both the tray bottom and sides.
