Knape and Vogt 18 inch over travel drawer slide is a side mount, ball bearing file drawer slide designed for projects that need firm hold-in and smooth extension. The 8505B 18 model is a side mount drawer slide that supports ball bearing progressive movement, so the drawer travel feels consistent through the entire stroke. This slide is part of the KV Model #8505 Series, which provides over travel, letting the drawer extend beyond the cabinet face to improve access to files near the back. The unhanded design allows either side installation, simplifying layout on both left and right drawers. The height of 3-51/64 inches gives a tall profile that supports file drawer applications where lateral stability is important during full extension. The drawer slide uses an Anochrome finish, which presents a neutral appearance suited to casework interiors in commercial or residential settings.
The 8505B 18 is a side mount drawer slide, so it is designed to mount on the cabinet sides and drawer sides rather than underneath the drawer box. Side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the space between the drawer and the cabinet, guiding box dimensions for a sliding fit that uses the full bearing race. The slide height of 3-51/64 inches contributes to side-wall contact, which helps maintain alignment on tall file drawers. The 32 mm pattern on the slide interfaces with cabinet systems that drill rows using the 32 mm system, which simplifies aligning mounting holes with standard line-bore layouts.
The Knape and Vogt 18 inch over travel drawer slide 8505B 18 is intended for file drawer applications where users need more than standard extension. Over travel lets the drawer extend beyond the cabinet face, improving visibility and reach to hanging files or stored contents at the rear of deeper drawers. The side mount layout matches cabinets that rely on side-mounted hardware instead of bottom-mount designs, aligning with typical file cabinet construction. Unhanded configuration means the same slide can be used on either side, simplifying stocking and reducing the chance of mixing left and right components during installation. The 3-51/64 inch height and ball bearing construction work together to support wide or tall drawers that see frequent opening cycles, helping them track along the race rather than twisting under load. The Anochrome finish suits interior cabinet environments by presenting a neutral metallic appearance that blends with common casework materials and hardware colors. As part of the KV Model #8505 Series, this 18 inch version aligns with other lengths in the line where standardized performance and geometry are desired.
The progressive movement on ball bearings distributes motion across bearing stages, which helps the drawer feel stable and controlled from the first inch of travel to full over travel extension. A retainer holding 3 bearings per inch of race supports multiple contact points along the slide, promoting smooth and quiet motion when the drawer is opened or closed in quick succession. Factory-attached drawer release clips with quick disconnect drawer members keep the release function integrated with the slide, which simplifies drawer removal during fit adjustments or cabinet service. The hold-in feature resists rebound when the drawer is pushed closed, keeping file drawers seated in the cabinet instead of drifting open from stored weight. Positive in and out stops define end positions for travel, helping protect the slide mechanism from being forced past its designed limits during heavy-handed use. Side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side gives fabricators a clear machining and shimming range, which aids in producing banks of drawers that operate consistently across a run of cabinets.
