The cap on most curtain wall glazing systems is a compression fit part that is not secure enough to hold our AP25 system on in a break-in attempt. We need to secure the curtain wall cap on first before installing AP25. This tutorial will give you the basics, but if you need help in the field, be sure to call our customer service line at 800-580-2303. Please also see the curtain wall shop drawing that should be included in your kit.
