Square & Rectangular FME Foam Pads — Debris Exclusion for Flat & Non-Round Openings (Safe-T-Sponge®)

For the openings a round plug can't cover

Square and rectangular FME foam pads seal off the flat, slotted, and oversized openings that round plugs don't fit — open trenches and channels, cable and pipe trays, sumps and drains, floor penetrations, large flat ports, and equipment cavities. Lay them in, seat them with a light compression fit, and pull them clear by the lift loops. Same debris-blocking foam as our round sponges, in the shapes that fit the rest of the job.

Choose your shape and finish

• Squares — 12"×12" up to 48"×48", for large flat openings and equipment tops.
• Laminated squares — same sizes with a tough protective top for repeated use and easy wipe-down.
• Rectangles & strips — from 4"×24" up to 24"×48", for long slots, troughs, trays, and channels.
• Lift loops for fast placement and removal; larger pads carry multiple handles.
• Low-halogen, low-metals foam — documented low-contaminant standard, independent lab testing, lot-number traceability; nuclear & fossil compatible.
• Patented design, made in the U.S.A.

Where they're used

Open trenches and grated channels, cable/pipe trays, sumps and drains, floor and deck penetrations, large rectangular ports, tank and vessel openings, and equipment cavities — anywhere a flat or non-round opening needs Foreign Material Exclusion during maintenance, outages, or fabrication.

Use & care (always follow site FME procedures)

• Size the pad so it seats with light compression across the opening; keep lift loops accessible and centered.
• Inspect before, during, and after use; account for and replace any damaged pad.
• Vacuum loose debris before removing the pad.
• Keep away from welding slag, grinding sparks, flame, and ignition sources (choose laminated where spark exposure is possible).
• Avoid acetone and alcohol-based solvents and oils. Don't soak or immerse. Don't step on or cut the pad.
• Attach a lanyard per your site standards where the opening is vertical or overhead.
