8091 4x4 Pocket Door Slide No Baseplate, 75lb Capacity, Ebony Black, 28

8091 Pocket Door Slide For Single Doors

8091 pocket door slide describes this Knape and Vogt 8091SP EB 28 flipper slide designed as top and bottom pocket door slides for a single door. This 28 inch length suits pocket door layouts that match the system's specified slide size for smooth travel. The 75 lb class rating supports heavy duty applications where door weight stays within that capacity. Maximum door dimensions of 72 inches tall by 26 inches wide define the working envelope so doors move correctly in and out of the pocket. The ebony black finish presents a dark, uniform look that blends into shadowed cabinet or media enclosures. A dual rack and pinion system in this model eliminates any potential for sag by synchronizing top and bottom slides. That rack and pinion action keeps the door tracking square as it moves, which helps reduce racking and binding over the full stroke.

Key Pocket Door Slide Details For Projects

• This 8091 pocket door slide is specified as top and bottom slides for a single door, so one matched set manages the full door movement and helps keep hardware layout straightforward.
• The 75 lb class rating supports heavy duty applications, allowing use on doors within that load range without overtaxing the slide mechanism during repeated cycling.
• Maximum door dimensions of 72 inches tall by 26 inches wide define a clear design window, helping layout match door size so the slide geometry stays in its intended operating range.
• The 28 inch slide length provides a predictable travel distance, which helps plan cabinet depth and pocket clearance around the slide stroke.
• The dual rack and pinion system eliminates any potential for sag by tying top and bottom slides together, which keeps the door edge aligned and reduces twist during operation.
• Precision ball bearing slides provide smooth and quiet operation, which supports controlled door movement in workspaces, media cabinets, or similar installations.
• The ebony black finish presents a dark visual profile, which helps the slide recede against darker interiors or shadow lines around the pocket opening.

Installation Layout And Pinion Shaft Interface

This Knape and Vogt 8091SP EB 28 slide uses a dual rack and pinion system that connects the top and bottom pocket door slides through a pinion shaft. Pinion shafts in 36, 48, or 72 inch lengths connect these slides and can be cut to an exact length as needed. That cut-to-length feature lets the installer match the shaft span to the cabinet or enclosure width while still maintaining synchronized motion between the two slides. The slide is described as no baseplate, so hinge base plates are not part of the 8091 configuration and are instead addressed separately in the system description. Ordering instructions specify KV8091 Step 1 as ordering the specific length of 8091, and Step 2 as ordering the pinion shaft, defining a clear two-part hardware selection process.

Real-World Use Of The KV8091 Pocket Door Slide

Where This KV8091 Pocket Door Hardware Fits Best

The 8091 4x4 pocket door slide sits in Knape and Vogt's pocket door hardware line for multimedia and workspace components. With a 75 lb class rating and maximum door dimensions of 72 inches tall by 26 inches wide, it suits heavier single doors sized inside that envelope. The 28 inch length works in cabinets or enclosures deep enough to accept that stroke, so the door can fully recess into the pocket. As part of the KV8091 family, this piece works with pinion shafts offered in 36, 48, or 72 inch lengths, which are cut to exact length to span between top and bottom slides within a cabinet run. Positioning these slides top and bottom on a single door sets up the rack and pinion link so both ends of the door move in unison.

Details That Support Alignment And Repeatable Motion

The dual rack and pinion system in this 8091 pocket door slide eliminates any potential for sag by positively driving both the top and bottom slides together. This synchronized movement helps keep the door vertical as it travels, which reduces side-loading on the slide members. Precision ball bearing slides add smooth and quiet operation, so the door can transition between open and pocketed positions with consistent resistance. The ability to cut the pinion shaft to exact length lets the installer match the drive connection to the cabinet width while retaining correct gear engagement. Ebony black finish keeps the hardware visually low profile around media and workspace openings, which matters when the door is open and the slide is partially visible. The ordering steps for KV8091, where Step 1 is ordering the specific length of 8091 and Step 2 is ordering the pinion shaft, define a predictable process so the slide and shaft are planned together around project dimensions.

Common Questions About The 8091 Pocket Door Slide

Selecting This 28 Inch Ebony Black Slide
