Standard specifications source: Made Ready Tool-Free Tray Liner spec sheet · February 2026. Drawing MRTLPP-SPEC.01.21.2026. Base width is dimension B for sidewall liners and A for flat liners. Full drawings and listed weights are in the source sheet.
Select a SKU to inquire. Confirm basket fit and availability. For BasorFil-specific geometry, request the matching design rather than selecting by nominal width alone.
Designed around the installation
The fastener is
already part of it.
The liner’s integral tabs engage the wire basket to hold the sheet in place. Sidewall configurations use preformed hinges so the sides can be folded on site.
It’s a practical approach to cable tray lining, with handling and installation considered together.
- Rigid material creates a continuous surface over basket crossbars.
- Integrated locking tabs secure the liner to the wire basket.
- Sheets ship flat for handling before installation.
- Sidewall variants fold along preformed hinges.
