rubber bumper glass from EPCO is a sliding door hardware component that press fits into a 1/4 in diameter hole in a side jamb to cushion the glass during door travel and contact. This rubber bumper is identified by manufacturer part 780, so it can be referenced consistently when matching to drawings, hardware schedules, or existing installations. Because it is designed for a 1/4 in dia. hole, it gives installers a clear drilling dimension when laying out the side jamb. The press fit design allows the rubber body to grip the 1/4 in hole in the jamb, so the bumper stays positioned where the glass makes contact. By cushioning the glass at that specific point, it helps reduce direct glass-to-jamb impact in normal sliding door operation.
This rubber bumper for 1/4 in hole is installed by press fitting it into a 1/4 in diameter hole drilled in the side jamb, giving a simple, defined interface between the bumper and the jamb. The 1/4 in dia. hole callout establishes the required bore size before the jamb is set, which helps integrate the bumper location into the door layout. Once pressed into the hole, the rubber body sits at the jamb face where the glass edge or panel meets, so it can cushion the contact point during sliding door use.
This EPCO 780 rubber bumper glass is used in a side jamb on a sliding glass door opening, where the jamb forms the vertical stop at the end of door travel. The bumper is press fit into a 1/4 in diameter hole in that jamb, so the drilled hole location effectively defines the glass stop position. Because it is classified as sliding door hardware, it fits into the same workflow as tracks, guides, and stops, giving the glass a cushioned point of contact at the jamb. In practice, the installer lays out the jamb, drills the 1/4 in hole at the required height for the glass edge, and then presses the rubber bumper into place so it sits ready for the moving glass pane.
The press fit into a 1/4 in dia. hole means the EPCO rubber bumper uses the hole size as its primary mounting control, so a standard 1/4 in drill bit establishes both fit and grip. Using that single dimension gives repeatable positioning from opening to opening, since the same bit and layout marks can be used across multiple jambs. Once pressed in, the rubber material holds in the jamb without separate fasteners at that point, so the bumper remains set where the glass contacts it during sliding. As part of the sliding door hardware group, this rubber bumper glass component helps define a consistent, cushioned end-of-travel for the glass, which supports a predictable stop location that aligns with the rest of the door hardware.
The EPCO 780 rubber bumper glass press fits into a 1/4 in diameter hole in a side jamb to cushion a sliding glass door where it contacts the jamb.
The rubber bumper mounts in the side jamb by press fitting into a 1/4 in diameter hole so it meets the glass edge at the end of door travel.
The 1/4 in diameter hole dimension lets installers drill with a standard 1/4 in bit, establishing the mounting size and glass stop location in the jamb.
The rubber bumper uses a press fit into the 1/4 in hole, so the rubber body grips the jamb at that bore and stays positioned at the glass contact point.
The rubber material cushions the glass where it meets the side jamb, reducing hard contact at that stop point during sliding door movement.
This rubber bumper glass is identified as EPCO manufacturer part 780, which provides a consistent reference for matching on future projects.
The EPCO rubber bumper glass, manufacturer part 780, provides a press fit solution for a 1/4 in dia. hole in a side jamb, giving sliding glass doors a cushioned contact point at the end of travel. By using the specified 1/4 in hole and side jamb location, it fits directly into sliding door hardware layouts where controlling the glass stop position and contact feel is important. For projects using glass and sliding door hardware together, this rubber bumper glass detail supports a clear, repeatable stop location in the jamb.
