CRL Standard Size Self-Closing Service Windows ship fully assembled, ready to glaze or factory glazed and ready to install. They are designed for heavy-duty commercial use such as drive-thru or walk-up service and are also ideal for interior applications needing enhanced security and performance. The Self-closing function is powered by a hydraulic mechanism concealed in the header. Standard size models are available in Satin Anodized or Duranodic Bronze finish. Different models are available with two types of bottom condition: half-track (no track under sliding panel for clear passage across counter by others) or stainless steel step-sill, with water-dam for exterior applications. CRL also quotes custom versions of these high-quality, popular windows.

CRL standard size self-closing models that ship unglazed come with two sets of glazing vinyl: one for ¼” glass, and one for ½” glass (the larger vinyl will also accept 9/16” glazing).

For 5/8” glazing vinyl (5/8” is maximum glass thickness for glazing a DW window with vinyl), CRL product # WV3865 can be ordered separately. It is sold by the foot, minimum order 100 feet.

For 3/8” glass, the provided ½” vinyl can be used if the edges of the glass are wrapped with CRL product # 982116X34GRY double-sided adhesive foam tape, with the backing left on the outer edge that enters the glazing vinyl channel. It is sold separately in 200-foot rolls.
