Common questions
What glass thickness does the CRL FV4DUC fit?
The CRL FV4DUC fits 3/8" glass. Measure your glass at the edge before ordering; a seal made for a different thickness will not stay on.
How do I install the CRL FV4DUC?
Press it into the channel by hand.
How do I cut the CRL FV4DUC 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 FV4DUC?
It comes in a 95" length.
Can I return the FV4DUC?
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.
