KV8505 18" Over Travel Hold-in anti-rebound Ball Bearing File Drawer Slides, Left Hand Side Mount Zinc Q-Pack - 8505-99 18

Knape And Vogt 18 Inch Over Travel Drawer Slide

Knape and Vogt 18 inch over travel drawer slide is a left hand cabinet member from the KV Model 8505 series that supports file drawer applications where precise movement and control are important. This 18 inch length cabinet member is part of a side mount ball bearing slide system, so it works in lateral file and cabinet layouts that use side-mounted runners. The slide provides over travel with a hold-in feature, so the drawer can extend beyond nominal length while staying pulled in at the closed position to reduce rebound. Progressive movement on ball bearings guides the travel, which helps maintain smooth, quiet action under normal office or shop use. Factory-attached drawer release clips with a quick disconnect drawer member simplify separation of the drawer from the cabinet member, which matters during installation and later adjustments. The anochrome finish supports a consistent appearance in typical cabinet interiors.

Key Working Details For Daily Drawer Use

• The 18 inch length establishes the slide stroke for file drawers, so installers can match cabinet depth and drawer box design to a known travel dimension.
• Side clearance of 1/2 inch plus 1/32 inch minus 0 each side defines the gap between drawer and cabinet, guiding drawer box sizing to achieve proper fit in side mount layouts.
• The 3-51/64 inch height, including the quick disconnect rail, sets the vertical profile of the cabinet member, which affects how it positions on the cabinet side and clears adjacent hardware.
• The hold-in feature is designed to prevent bounce back at closure, so drawers stay seated in normal use instead of drifting partially open in response to movement.
• Positive in and out stops limit the travel at both ends, which helps protect the slide race and drawer structure from over-extension impacts during repeated operation.
• A retainer that holds 3 bearings per inch of race supports smooth motion along the full length, which matters for file drawers that carry weight over frequent open and close cycles.

Side Mount Installation And Fastener Details

This cabinet member is part of a side mount, ball bearing drawer slide system, so it runs along the cabinet side rather than beneath the drawer. The 32 mm pattern is present, which aligns the slide with cabinet side drilling layouts built around the 32 mm system. Recommended fasteners are #7 x 5/8 inch Phillips pan head screws, tying the slide to common installation hardware that matches the hole sizing. The quick disconnect drawer member works with factory-attached drawer release clips, allowing the drawer member to detach from the cabinet member to support fitting, removal, or service without dismantling the entire drawer box.

How This 8505 Series Member Works In Cabinets

Use In File Drawers And Side Mount Layouts

The KV Model 8505 cabinet member is made in the USA and belongs to a side mount, ball bearing slide family used in file drawers. Its 18 inch length targets cabinet openings that match standard file drawer depths, so lateral or pedestal file units can be built around this stroke. Since the slide uses side clearance of 1/2 inch plus 1/32 inch minus 0 per side, cabinetmakers can size drawer boxes while holding predictable clearances for file folders and hanging systems. The 3-51/64 inch overall height, including the quick disconnect rail, creates a tall bearing track along the cabinet side, which helps support taller file drawer sides. The anochrome finish provides a consistent metal surface along the race, matching other anochrome components inside casework.

Movement, Hold-In Control, And Quick Disconnect

The 8505 series cabinet member uses progressive movement on ball bearings, meaning the ball retainer travels in stages to keep motion controlled through the entire extension. A retainer holding 3 bearings per inch of race provides a dense bearing pattern, supporting even load transfer along the slide. Positive in and out stops define the travel limits at both ends, so the drawer stops consistently without over-running the race. The over travel characteristic allows the drawer front to move beyond the nominal slide length, making files at the back of the drawer easier to access in normal cabinets. The hold-in feature is designed to prevent bounce back from the closed position, so drawers stay fully shut after being pushed in. Factory-attached drawer release clips are paired with a quick disconnect drawer member, helping installers separate or reconnect the drawer and cabinet members efficiently during fitting or when casework needs to be serviced.
