## Common questions

**Does the S1LB depend on glass thickness?**

No. The S1LB 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](https://idealshowerdoors.com/store/measure).

**What gap does the S1LB seal?**

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

**How do I install the CRL S1LB?**

Attach the base with clear silicone, not tape.

**How do I cut the CRL S1LB 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](https://idealshowerdoors.com/store/p/pts89) or a fine-tooth hacksaw. The snips give a clean, straight or angled cut in one squeeze.

**How long is the S1LB?**

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

**Can I return the S1LB?**

No. All sales are final: due to the nature of shipping these long seals, items cannot be returned. Measure your [glass thickness](https://idealshowerdoors.com/store/measure) and check the suggested gap before you order; our measuring guide shows how.
