CRL component items for our Sharyn Frameless Glass Pass-Thru Window are ideal for use as replacement parts, or for units you wish to fabricate yourself. Stock lengths of the Extrusions, individual parts, and accessory hardware provide all of the options you need to build your own inline enclosures for 1/4" (6 mm) glass. You can also send our Transaction Department a drawing of the enclosure, we can also quote a custom unit.
