Center Mount 50 lb Nylon Roller Slides give a 3/4 extension under-drawer solution that supports drawers up to 50 lb, so medium-load cabinet drawers open smoothly without over-extending the slide. As a center bottom mount drawer slide, this Knape and Vogt 1175P ZC 22-5/8 model sits under the drawer instead of on the sides, which keeps the drawer sides available for tight clearances or design details. The 22-5/8 inch length matches typical cabinet depths where a full-depth center rail is needed, so the slide supports the drawer along its run. A 1 inch height profile keeps the slide low under the drawer, which helps when vertical space under the box is limited. USA manufacturing on this KV Model #1175 gives consistent dimensions that align with the stated clearances for repeat installs.
This Knape and Vogt center bottom mount drawer slide is designed as an under drawer mount, so it supports the drawer from a single center rail. The nylon roller slide mounts with staples or screws, which gives flexibility on shop equipment and preferred fastening method. With side clearance at 1/8 inch each side, the drawer box width must be set so the assembled drawer and clearances match the cabinet opening, allowing the center rail to guide the movement. The drawer must be 1-1/4 inch shorter than cabinet depth, so installers size drawer depth and rail length together. Recommended fasteners are #6 x 13/32 inch Phillips pan head (KV1300-83), which fit the slide holes and keep the profile low against the wood.
This center bottom mount drawer slide fits applications that call for a single under-drawer guide, such as cabinets using a center rail instead of side-mount hardware. With the 22-5/8 inch length, it suits cabinets where the internal depth works with a drawer that is 1-1/4 inch shorter than cabinet depth, because the rail is cut to size to match that dimension. The 1/8 inch side clearance each side means it is appropriate for drawer openings laid out with a total 1/4 inch wider than the drawer box, which allows the center-mounted slide to run without side binding. The 1 inch height allows it to tuck under drawer bottoms in face-frame or frameless boxes where structure under the drawer limits hardware height. As a 50 lb slide, it matches drawers built for typical household contents or light shop items within that weight range.
The nylon roller slide design affects how the drawer feels in motion, as the rollers track along the rail to give a consistent pull across the 3/4 extension, which installers can rely on when building multiple matching cabinets. Having the slide mount with staples or screws means the same product can be used in shops that prefer quick staple attachment or in jobs where screws are standard, so one specification covers different workflows. The specified drawer depth - being 1-1/4 inch shorter than cabinet depth - ties directly to how far the drawer front sits from the case front, which helps align gaps and faces across a bank of drawers. The rail cut to size feature matters when cabinet depths vary, because the installer can trim the rail at the jobsite while still using the same Knape and Vogt 1175P ZC 22-5/8 slide model. Side clearance at 1/8 inch each side is also critical, since drawer boxes built to that tolerance will track squarely on the center mount rail without rubbing cabinet sides, reducing call-backs due to sticking drawers.
The KV 1175P ZC 22-5/8 is a center bottom mount drawer slide with nylon rollers, so it supports the drawer from underneath along a central rail.
These Center Mount 50 lb Nylon Roller Slides are rated for 50 lb, which suits typical residential and light-duty drawers built within that load range.
This Knape and Vogt 1175P slide provides 3/4 extension, so most of the drawer opens while part of the slide stays engaged inside the cabinet.
The drawer needs 1/8 inch side clearance on each side and must be 1-1/4 inch shorter than cabinet depth, so the slide and rail align with the case.
The nylon roller slide mounts with staples or screws, and the recommended fasteners are #6 x 13/32 inch Phillips pan head (KV1300-83).
The rail on this center bottom mount drawer slide is cut to size, so it can be trimmed to match the cabinet depth for proper drawer positioning.
The KV 1175P ZC 22-5/8 center bottom mount drawer slide from Knape and Vogt provides a 50 lb, 3/4 extension under drawer solution with defined side clearance, specified drawer depth, and a rail cut to size. Those details let installers plan drawer box dimensions and cabinet depths around known numbers, so multiple units in a project share the same hardware layout. For projects needing a USA-made center mount nylon roller slide with these dimensions, this model gives a straightforward, repeatable option.
