Knape and Vogt 28 inch drawer slides in the 8900 Series are side mount, full extension ball bearing slides that support extra heavy-duty applications, so they are suited to drawers that see demanding loads and frequent use. The zinc finish on these slides provides a clean, neutral surface that works well in utility cabinetry where appearance and corrosion resistance both matter over time. Their non-handed design means each slide works on either side of the drawer, which simplifies layout on the bench and cuts down on orientation errors during installation. These slides are non-disconnect, so the drawer member stays engaged with the cabinet member in service, which helps maintain alignment where drawers are heavily loaded. The 28 inch length gives you a full extension stroke on cabinets sized for that depth, allowing full access to the drawer interior during daily work.
The KV Model #8900 in 28 inch length is a side mount slide with a specified side clearance of 3/4 inch, which gives you a clear target when sizing drawer boxes relative to cabinet openings. The slide height is 3 inches, so casework and drawer side design can be laid out to allow for that vertical space along the cabinet interior. These slides use a non-handed, non-disconnect format, so layout focuses on accurate spacing rather than orientation changes, which can streamline repetitive installs. The recommended fastener on the cabinet member is a #10 flat head machine screw, giving installers a defined fastener type for securing the slide to cabinet structures designed for machine screw attachment.
The 8900 Series side mount drawer slides are described for extra heavy-duty applications, so the 28 inch version fits drawers that must handle significant loads in workshop, utility, or commercial cabinetry. With full extension travel, these slides allow deep drawers to come fully forward, which is helpful when drawers store heavier items that are easier to lift out when fully exposed. The 3 inch height and side mount configuration suit robust drawer box constructions where substantial slide sections are expected to support load and resist racking. A 3/4 inch side clearance specification ties directly into framing and drawer sizing, which is especially important when building a bank of wide drawers that need consistent side gaps across all openings.
The non-handed design of the 8900B 28 means the same slide model can be used on either side, which streamlines layout for runs of drawers and reduces the chance of fitting the wrong hand on busy installs. Heavy duty ball bearings are specified to carry the heaviest loads without sticking, which supports repeatable drawer motion even after many open and close cycles in load-bearing service. The non-disconnect feature keeps drawer and cabinet members engaged, which maintains slide alignment and helps drawers track square when loaded in heavy-duty environments. Specified use of a #10 flat head machine screw on the cabinet member gives installers a clear fastener style, helping achieve consistent holding power when fastening into appropriately prepared cabinet structures.

The KV Model #8900 specifies 3/4 inch side clearance, which guides how you size drawer boxes relative to cabinet openings for proper slide fit.
The recommended fastener on the cabinet member is a #10 flat head machine screw, giving a defined fastening method when the cabinet structure is prepared for machine screw attachment.
