Common questions

Does the S1LBT2 depend on glass thickness?

No. The S1LBT2 mounts to the glass edge or wall, so choose it by the gap it closes (1/16" to 3/16") rather than by glass thickness.

What gap does the S1LBT2 seal?

It closes gaps from 1/16" to 3/16". Measure with the door closed.

How do I install the CRL S1LBT2?

It comes with clear tape already applied: clean the surface, peel the liner and press it in place.

How do I cut the CRL S1LBT2 to length?

Measure the glass edge where the seal goes, then cut the seal to that length with plastic trim snips like the CRL PTS89 or a fine-tooth hacksaw. The snips give a clean, straight or angled cut in one squeeze.

How long is the S1LBT2?

It comes in a 95" length that you cut to fit your door.

Can I return the S1LBT2?

No. All sales are final: due to the nature of shipping these long seals, items cannot be returned. Measure your glass thickness and check the suggested gap before you order; our measuring guide shows how.
