If you're designing your glass doors from scratch, and have the liberty of determining the rabbet depth, these simple, affordable glass retainers represent a great value. Each has a small knob that extends down into the rabbet 1/8'' and presses against the glass to prevent rattling. Offset is 1/8''. So, for example, if your glass is 1/8'' thick, then your rabbet would be 1/4'' deep. If you have a drill press, deeper rabbets can be accommodated by insetting the glass clips into the frame using a Forstner bit. Each pack contains eight glass clips, plus screws.
