Knape and Vogt 18 inch over travel drawer slides give a file drawer extra travel beyond the cabinet front, which helps expose rear files and contents for easier access in tight installations. This 8505 Series model is a side mount ball bearing file drawer slide, so it suits applications that call for a side-mounted, smooth-running slide in office or storage cabinetry. The slide height of 3-51/64 inches sets the vertical space these slides need in the drawer opening, guiding layout when working around existing partitions or rails. Side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the fit between the drawer and the cabinet, providing a clear target when sizing drawer boxes to avoid binding or racking. The hold-in anti-rebound feature works with the ball bearing system to resist bounce back when closing, which helps drawers stay shut in everyday use.
This 8505P 18 side mount drawer slide is designed as a side mount ball bearing slide, aligning with cabinet constructions that rely on side panel engagement rather than bottom or center mounting. The 32 mm pattern on the slide supports layouts that follow 32 mm cabinet drilling systems, which streamlines alignment in modular casework using that standard. Factory-attached drawer release clips provide a quick disconnect drawer member, so the drawer can be separated from the cabinet members at the clips for finishing or service and then re-installed on the same slide tracks. Positive in and out stops integrated into the slide help control the end of travel in both directions, which supports predictable extension and retraction in multi-drawer banks.
The 18 inch over travel design suits file drawers that need to open past the cabinet front, particularly for full-depth files in desks, pedestals, and casework aligned with the Knape and Vogt 8505 Series. The 3-51/64 inch slide height and specified side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side give clear framing dimensions, which is useful when sizing drawer sides to avoid interference with cabinet openings. As a side mount ball bearing file drawer slide in the Side Mount Drawer Slides product class, it fits applications where the drawer rides along the cabinet side walls rather than on undermount hardware. The file drawer focus supports storage that often carries paperwork weight, and the progressive movement on ball bearings helps maintain controlled travel along the full extension path.
The retainers that hold 3 bearings per inch of race work with progressive movement on ball bearings to distribute load along the slide members, which contributes to smooth and quiet motion during opening and closing. The over travel feature extends the drawer beyond standard full extension, allowing better hand access to file folders at the back of the drawer, which is practical in deep cabinets where rear documents are otherwise harder to reach. Hold-in anti-rebound behavior supports the closed position by resisting bounce back after closure, which matters in file storage where drawers benefit from staying shut between uses. The anochrome finish helps maintain a consistent metal surface across the slide components, providing a clean appearance that suits interior cabinet environments. As a Knape and Vogt 8505 Series slide made in USA, this model aligns with projects that specify that brand and origin for coordination with other 8505 components.
The 8505P 18 is a Knape and Vogt 18 inch over travel side mount ball bearing file drawer slide, so it mounts to the cabinet sides and supports file drawer applications.
The over travel on this 18 inch slide lets the drawer extend past the cabinet front, improving access to files at the rear of the drawer in deeper cabinets.
These slides require side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side and a slide height of 3-51/64 inches, guiding drawer and opening sizing.
Factory-attached drawer release clips provide quick disconnect drawer members, allowing the drawer to be detached from the cabinet members for finishing or service and then reattached.
The hold-in anti-rebound feature helps the drawer stay closed by resisting bounce back after closing, which is valuable on frequently used file drawers.
The 8505P 18 slide has a 32 mm pattern, which aligns with cabinet systems drilled on 32 mm centers and supports consistent hole spacing during installation.
Choosing this Knape and Vogt 18 inch over travel drawer slide ties file drawer performance to defined dimensions and movement. The 8505 Series side mount ball bearing design, 32 mm pattern, and hold-in anti-rebound behavior combine to support predictable travel and closure in file storage cabinetry. When a project calls for 18 inch length, over travel, and the specified clearances, this 8505P 18 model provides the matching slide geometry and motion characteristics for those requirements.
