Why we publish CRL cross references

Every glazier in South Florida knows the CRL number of the hinge they install most. That number is muscle memory, and switching suppliers usually means losing it.

So we built our catalog the other way around. Type the part number you already use into our cross reference tool and we show you the Singular equivalent, the match quality, and the honest differences in the spec, side by side with the price.

Exact matches are marked exact only when we have compared the load rating, the glass thickness range, and the mounting pattern. Anything less is labeled equivalent or partial, with notes. Your reputation rides on the hardware, so the claims stay honest.
