Sliding door knobs with screws give sliding panels a defined pull point so doors open and close with control instead of relying on the door edge. This EPCO set uses a 15/32 inch diameter knob that concentrates hand force in a small area, which helps move the door smoothly along the track. The knob projects 3/4 inch from the mounting surface, creating enough clearance for fingers while keeping the profile tight to the door face in tight tracks or overlapping panels. Aluminum construction keeps the part light yet rigid, which supports easy movement of typical sliding door panels in builders hardware applications. The satin black anodized finish gives the grip a dark, low-glare surface that visually blends with many track and frame systems and helps reduce the appearance of handling marks in normal use.
The 15/32 inch diameter on each EPCO knob defines the footprint you drill for, so the pull seats properly on the sliding door shoe and stays aligned with the track. A 3/4 inch projection from the mounting surface sets how far the grip stands off the door, which influences finger clearance when doors overlap in a multi-panel run. The set is paired with #6-32 x 3/4 inch and 6-32 x 5/8 inch screws, so the knob threads match a 6-32 interface commonly used in sliding door hardware and allow use with different door or shoe thicknesses. A rubber bumper is part of the set, giving the sliding edge a cushioned contact point that can soften door-to-frame contact in normal operation.
This EPCO GP20-BL knob set is intended for builders hardware and sliding door hardware applications where a defined pull point is needed on a moving panel. The design is described as ideal for mounting to a sliding door shoe identified as part 743, which places the knob directly on the shoe that carries the door in the track. Locating the 15/32 inch diameter knob on the sliding door shoe keeps the hand grip aligned with the door centerline, helping the panel travel straighter along the track during opening and closing. The 3/4 inch projection provides a consistent stand-off from the shoe, which is useful when several doors share a track and need predictable clearance between pulls.
The 15/32 inch diameter defined for the knob determines the contact area for the user, which supports a repeatable feel every time the door moves. The 3/4 inch projection fixes the grip depth so installers can anticipate clearance when planning overlapping doors or returns near adjacent walls and frames. The aluminum material keeps the knob light relative to door size, which helps avoid adding significant mass at the edge of sliding panels and supports smooth travel on the track. satin black anodized finish gives the knob a uniform dark tone that matches many black sliding door tracks and shoes, promoting a consistent look across a full run of hardware. The use of #6-32 x 3/4 inch and 6-32 x 5/8 inch screws ties the knob to a common thread standard, which simplifies selecting the screw length that best matches the specific door or shoe thickness within the range those screws serve. The rubber bumper in the set creates a resilient contact surface, which can help absorb minor impact when the sliding door reaches its stop.
The EPCO GP20-BL sliding door knob has a 15/32 inch diameter, giving a compact grip area that suits narrow sliding door stiles and keeps pulls from interfering with adjacent panels.
The knob projects 3/4 inch from the mounting surface, providing finger clearance for a secure pull while keeping the profile low so doors can pass closely in shared tracks.
The EPCO GP20-BL knobs are made from aluminum with a satin black anodized finish, combining a lightweight body with a dark surface that coordinates with many sliding door systems.
The knobs are described as ideal for mounting to a sliding door shoe using part 743, positioning the pull directly on the shoe that guides the door in the track.
The knob set uses #6-32 screws in 3/4 inch and 5/8 inch lengths, providing a common thread interface used across many builders hardware sliding door components.
The rubber bumper in the GP20-BL set offers a cushioned contact point, which can soften contact when the sliding door reaches the end of travel in normal operation.
The EPCO GP20-BL sliding door knobs with screws combine a 15/32 inch diameter grip and 3/4 inch projection with aluminum construction and a satin black anodized finish, supporting controlled movement and a consistent look on sliding door shoes such as part 743. Using the supplied 6-32 screw sizes and rubber bumper, these knobs tie directly into standard sliding door hardware layouts so installers can match pulls, track components, and stops within one system. Select this knob set when a compact, dark-finished pull is needed on aluminum-based sliding door hardware in builders hardware installations.
