KV8500 18" Full Extension Hold-in anti-rebound Ball Bearing File Drawer Slides, Left Hand Side Mount Zinc Q-Pack - 8500-99 18

Knape And Vogt 18 Inch File Drawer Slide

Knape and Vogt 18 inch file drawer slides provide a full extension travel, so the drawer opens its entire length and gives clear access to stored files along the slide. This model 8500-99 18 is a left hand side mount design, so it installs on the cabinet side wall rather than under the drawer. The slide uses ball bearing construction, which supports smooth motion as the bearings roll, helping the drawer move cleanly under load. A hold-in anti-rebound feature is built into the mechanism, so the drawer stays closed at the back of travel, which matters when the cabinet sees frequent opening and closing. Positive in and out stops are part of the slide design, so the drawer travel is controlled at both ends of the cycle, helping protect the drawer, face, and cabinet from over-travel impacts.

Key Working Details For The KV 8500 Slide

• The 18 inch length defines the drawer travel, so file drawers built around this slide can open the full designed depth for visibility and access.
• A side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side sets the fit between drawer and cabinet, so casework can be machined to a repeatable gap for the side mount layout.
• The slide height of 3-51/64 inch, including the quick disconnect rail, sets the vertical space the hardware occupies, which helps with planning drawer box height and stack spacing within a cabinet.
• The 32 mm pattern is supported on this slide, so case sides bored on that system line up with mounting holes, speeding layout when using line-bored cabinets.
• Factory-attached drawer release clips with quick disconnect drawer members are part of the slide, so the drawer can be released at those clips, allowing removal or installation without dismantling the cabinet.
• The retainer holding three bearings per inch of race supports smooth and quiet motion, so file drawers feel controlled during travel rather than loose or rough.

Mounting, Fasteners, And Extension Details

This 18 inch left hand side mount ball bearing slide is specified for a side mount installation, so it fastens directly to the cabinet side. The recommended fasteners are #7 x 1/2 inch Phillips pan head screws (BST1/2X7-2C), which match the slide hole sizing, helping the hardware seat properly along the mounting pattern. The slide delivers full extension, so when installed to the cabinet members and drawer members, the drawer box can move fully forward to its design stop, keeping files reachable without reaching past the front rail.

Using The 8500-99 18 Slide In Cabinet Work

Where This 18 Inch Side Mount Slide Fits

The Knape and Vogt model 8500-99 18 is identified as a file drawer slide, so it is intended for drawers that carry hanging or stored files. Its 18 inch length suits cabinets planned around that depth, so the drawer box can be sized to hold files front to back while staying on the slide travel. The side mount design places the cabinet members along the interior cabinet walls, so the drawer sides remain parallel to the case, which is typical for lateral or vertical file storage. With a side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side, this slide works with drawer boxes built to leave that margin, so the hardware has the space it needs to run without binding. The slide height of 3-51/64 inch, including the quick disconnect rail, defines the minimum vertical space for the hardware lane, so designers can plan drawer box heights and clearances above the slide. The 32 mm pattern support means that cabinets drilled on that system can align slide mounting holes to the boring pattern, which speeds layout in production shops using that standard. The available Anochrome finish provides a uniform appearance on the slide members, which matters when the hardware is visible on open drawers in commercial or office installations.

Details That Support Repeatable Drawer Performance

The 8500 series uses ball bearings with a retainer that holds three bearings per inch of race, so each inch of slide travel carries multiple bearing points, which spreads load and helps the drawer move smoothly along its path. Factory-attached drawer release clips with quick disconnect drawer members are part of the system, so once mounted, the drawer can be separated from the cabinet members at those clips, which helps during finishing, adjustment, or later service. The hold-in anti-rebound feature is designed to prevent bounce back at the closed position, so when the drawer is pushed shut, the mechanism resists the drawer rolling forward again, which matters in offices or shops where drawers are used repeatedly through the day. Positive in and out stops are integrated into the slide, so travel is controlled both at the fully closed end and at the full extension end, which helps protect fronts and hardware from overextension impacts. The recommended #7 x 1/2 inch Phillips pan head screws (BST1/2X7-2C) match the slide design, so the heads seat properly within the mounting holes and help keep the members aligned along the cabinet and drawer. This model is part of the KV 8500 line and is made in the USA, so it matches other 8500 series components in layout and function across a project.
