KV8500 22" Full Extension Hold-in anti-rebound Ball Bearing File Drawer Slides, Left Hand Side Mount Zinc Q-Pack - 8500-99 22
Description
Knape And Vogt 22 Inch File Drawer Slides
Knape and Vogt 22 inch file drawer slides are 8500 Series side mount ball bearing slides designed for file drawer applications where controlled extension and return matter. The 22 inch length sets up a predictable travel distance for standard drawer depths in casework using similar proportions. Full extension operation allows the file drawer to travel out to its full rated length so the cabinet opening gives access along the drawer length. The side mount configuration positions the slide along the cabinet sides, aligning with typical file drawer construction using parallel side panels. A hold-in anti-rebound feature is built into the slide design to keep the drawer held in the closed position, reducing the chance of the drawer bouncing back open after closure. These slides are part of the KV Model 8500 line made in USA, which identifies the manufacturing origin and series family for matching to other 8500 components.
Working Features For File Drawer Performance
- The side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the required gap between drawer and cabinet, which guides case construction so the slides track smoothly without racking against the drawer sides under load.
- The slide height of 3-51/64 inch, including the quick disconnect rail, sets the vertical space needed along the drawer side, letting builders plan drawer box height and internal file clearances around the slide envelope.
- The 32 mm pattern mounting layout aligns with system-drilled case sides following the 32 mm system, so cabinet sides drilled on that pattern can position mounting screws in a repeatable grid for easier production work.
- Factory-attached drawer release clips with quick disconnect drawer members create a slide interface that can be separated, so installers can remove the drawer member from the cabinet member when fitting or servicing drawers.
- The hold-in feature that prevents bounce back works at the end of travel, so when the drawer is pushed closed the mechanism resists a return movement that might otherwise leave the drawer partially open.
- Positive in and out stops limit travel at both ends of the stroke, protecting the slide from over-travel and helping the drawer stop consistently at full extension and full closure.
Mounting And Fastener Details For Installation
The 8500 Series side mount design uses cabinet members fixed to the case sides and drawer members fixed to the drawer sides, forming a full extension slide assembly along each side. Recommended fasteners are #7 x 1/2 inch Phillips pan head screws (BST1/2X7-2C), which match the slide holes and thickness so the head seats properly in the mounting pattern. The specified 1/2 inch plus 1/32 inch minus 0 inch side clearance per side ties directly into case layout, so builders dimension drawers narrower than the opening by the combined clearances for both sides. The quick disconnect rail height of 3-51/64 inch factors into vertical placement, because the slide height can influence how the drawer bottom aligns with cabinet components such as stretchers or file rails.
Using KV 8500 Full Extension Slides In Projects
Where These 8500 Series Slides Are Applied
The 8500 Series designation identifies these as Knape and Vogt side mount ball bearing slides suited to file drawer use where full extension is required. The cabinet member in the 8500-99 22 configuration is a left hand component, which fits the left interior side of a cabinet opening when paired with the matching right hand member in an assembly. The side mount format works with drawer boxes that present flat exterior sides, so the slide can fasten directly along the length of the drawer. The 22 inch length matches casework layouts where the cabinet depth and drawer depth are designed around that slide travel, helping maintain consistent overlay or inset relationships at the front. The 32 mm pattern mounting can align with production cabinets drilled on a system line, which supports repeatable positioning across multiple openings in the same run of casework.
Why These Details Support Consistent Drawer Action
The ball bearing construction in these file drawer slides uses a retainer that holds three bearings per inch of race, giving multiple contact points along the slide length so the moving members track smoothly under typical side mount loading. That bearing density supports consistent motion along the full 22 inch extension, which matters when drawers are loaded along their length with hanging files or stored material. Positive in and out stops engage at the ends of the stroke, so the drawer does not overrun the slide and the extension stops at the designed position every time. The hold-in anti-rebound function at closure works with those stops by resisting a return movement after the drawer is pushed shut, which helps the front stay aligned in the closed plane of the cabinet. Factory-attached drawer release clips with quick disconnect members allow the drawer to be separated from the cabinet members for case finishing or adjustments, then re-engaged on the same track pattern. The specified 1/2 inch plus 1/32 inch minus 0 inch side clearance and the 3-51/64 inch height, taken together, give fixed layout dimensions so builders can repeat the same fit across a bank of file drawers using the same slide model.
Common Questions About 8500-99 22 Slide Details
What type of drawer slide is the 8500-99 22?
The 8500-99 22 is a Knape and Vogt 8500 Series side mount ball bearing file drawer slide, so it mounts to cabinet sides and supports full extension movement for file drawers.
What is the length of these Knape and Vogt slides?
The Knape and Vogt 22 inch file drawer slides have a 22 inch length, giving drawers a full extension stroke sized for casework built around that depth.
How much side clearance do these drawer slides require?
The 8500-99 22 slides use 1/2 inch plus 1/32 inch minus 0 inch side clearance on each side, guiding the gap between the drawer and cabinet opening for proper tracking.
What fasteners are recommended for installing these slides?
The 8500 Series slides specify #7 x 1/2 inch Phillips pan head screws (BST1/2X7-2C), which match the slide mounting holes and thickness for secure attachment.
How does the hold-in feature affect drawer operation?
The hold-in feature on these hold in anti rebound drawer slides keeps the drawer in the closed position, limiting bounce back so fronts stay aligned after closure.
What is the height of the 8500 Series slide with rail?
The Knape and Vogt 8500 Series slide has a height of 3-51/64 inch including the quick disconnect rail, which defines the vertical space required along the drawer side.
Selecting These Slides For File Drawer Runs
The 22 inch left hand cabinet member 8500-99 22 from the KV 8500 Series offers full extension, a defined 1/2 inch plus 1/32 inch minus 0 inch side clearance per side, and a 3-51/64 inch height with quick disconnect rail. The hold-in anti-rebound function, ball bearing race with three bearings per inch, positive stops, and 32 mm pattern collectively give predictable layout and motion. For projects calling for a made in USA side mount file drawer slide built around these dimensions and features, this model aligns cabinet design and drawer action on a single known standard.
