Knape and Vogt 8400 drawer slide defines this 8 inch full extension, ball bearing, side mount slide built for precise drawer travel in short-depth applications. The 8 inch length supports compact drawers where space is tight but full access to contents is still required during normal use. Full extension construction lets the drawer travel its full length, so the back of the drawer is reachable without over-travel that could stress the cabinet members. The side mount design locates the slide on the drawer sides, which keeps the cabinet floor clear for straightforward case construction. This slide is part of the KV 8400 Series, so it follows a consistent design approach that helps keep layouts uniform when multiple drawer sizes are used in the same project.
This KV Model 8400 8 inch slide is specified as a side mount unit with a side clearance of 1/2 inch, plus 1/32 inch, minus 0 inch on each side, so cabinet openings can be planned to that clearance for fitting drawer boxes. The slide height is 1-13/16 inch, which helps determine the minimum drawer side height where the member is fastened. A 32 mm pattern is provided, aligning hole positions on the slide with systems based on 32 mm increments for cabinet case drilling, which supports more repeatable boring and hardware placement across cabinet runs.
This 8 inch ball bearing drawer slide in the 8400 Series is sized for compact drawers where an 8 inch nominal slide length meets the depth requirement. The specified side clearance of 1/2 inch, plus 1/32 inch, minus 0 inch on each side works with drawer boxes built to leave that running clearance between drawer sides and cabinet walls, which is useful when standardizing box widths. With a slide height of 1-13/16 inch, the installer can relate the member height to drawer side dimensions so there is enough material for fastener placement without crowding the top edge of the side. The 32 mm pattern specification lets this slide integrate into cabinets laid out on a 32 mm system, so boring patterns in the case can align to incremental rows while still accommodating this specific member height.
The unhanded configuration means the same 8400B 8 part number serves both sides of the drawer, removing hand-specific stock and reducing matching steps during installation, which supports smoother assembly lines and service visits. Lever disconnect provides a simple mechanical way to separate drawer and cabinet members, so drawers can be removed during finishing, transport, or interior work and then re-set on the same slide members without changing adjustment points. The hold-in, anti-rebound detail works along the slide travel to help the drawer stay shut once it reaches its closed position, which is useful when aligning a row of fronts where uniform gaps depend on drawers remaining fully seated. The ball bearing design, together with the ball retainer latch, maintains organized bearing movement as the members cycle, which matters for drawers that are opened and closed repeatedly in normal shop, office, or residential environments.
The 8400B 8 is a Knape and Vogt 8400 Series 8 inch full extension, side mount, ball bearing drawer slide, so it supports smooth linear travel and full-length extension for compact drawers.
The 8400B 8 slide uses a side clearance of 1/2 inch, plus 1/32 inch, minus 0 inch on each side, which guides the opening size when sizing drawer boxes relative to cabinet width.
The 8400B 8 slide has a height of 1-13/16 inch, which helps determine the minimum drawer side height and positioning of fasteners along the drawer member.
The 8400B 8 lever disconnect lets the drawer member separate from the cabinet member, which speeds drawer removal and reinstallation during finishing, alignment, or interior cabinet work.
The 8400B 8 slide is specified with recommended fasteners of #7 x 1/2 inch Phillips Truss Head screws, which match the hole sizing and support secure mounting into cabinet and drawer members.
The 8400B 8 slide is noted with a 32 mm pattern, meaning its hole locations are arranged for use with cabinet systems that follow a 32 mm drilling layout.
Choosing the 8400B 8 full extension slide locks in an 8 inch Knape and Vogt 8400 Series side mount member with defined 1/2 inch, plus 1/32 inch, minus 0 inch side clearance and 1-13/16 inch height, so drawer boxes and cabinet openings can be laid out accurately around those fixed dimensions.
