429 Steel Round Groove Sheave describes an open wheel sheave from Knape and Vogt that is built for use in builders hardware sheaves and tracks applications. The open wheel design exposes the ball bearing, which lets the wheel turn with reduced friction so doors or panels move smoothly along the track. Steel finish on the sheave provides a hard-wearing running surface, which supports consistent rolling over time in typical shop or jobsite environments. Being part of the Sheaves and Tracks product class links this wheel to sliding, guiding, or redirecting movement where a round groove profile is required. The Knape and Vogt brand connection gives installers a recognizable source when they want to match existing builders hardware or keep to a known hardware line on repeat projects.
The Web Description calls out "Use #4 Flat Head Wood Screw (not included)," which points to a specific screw size and head style for fastening this sheave. That detail means the mounting hole and hub are suited to a #4 diameter, helping installers select a driver bit and predrill size that match the intended fit of the sheave pivot. The flat head specification signals a countersunk bearing surface, so the screw head can sit flush into the support member while the wheel turns around the shank. This arrangement supports a compact mounting profile that allows the 429 Steel Round Groove Sheave to rotate freely without the head interfering with the wheel path.
The Category entry of Builders Hardware combined with Product Class Sheaves and Tracks positions this 429 Steel Round Groove Sheave for door, panel, or guide assemblies where a wheel rides against a track or guiding surface. Its round groove geometry gives the wheel a curved running channel, which suits mating with rounded track edges or cables where a matching profile is important for controlled movement. The steel finish provides a metallic contact surface that holds up under repeated rolling cycles, making it suitable for applications where the sheave sees frequent passes along the same track. Because the Brand is Knape and Vogt, this part can align with broader Knape and Vogt hardware systems used across cabinets or other structures, helping maintain consistent component sourcing across multiple openings or units.
The SAP Description of SHEAVE, BALL BEARING highlights that the 429 STL sheave centers on a ball bearing core, which lets the wheel rotate with less resistance around its mounting screw. That low-friction rotation helps reduce effort when sliding doors or guided members and can lessen wear on the track surface over time. The Web Description notes an open wheel sheave, meaning the ball bearing area is not enclosed by an added housing, so the rotating elements sit directly in line with the mounting stack, keeping the assembly compact. This same Web Description points to the use of a #4 Flat Head Wood Screw, so the pivot is defined around a common wood screw size, aiding repeatable installations where multiple sheaves are set to the same centerline. The steel finish ensures that the wheel face presents a uniform material to the mating track or guide, which supports consistent tracking behavior from one end of travel to the other.
The 429 Steel Round Groove Sheave is an open wheel sheave from Knape and Vogt used in builders hardware sheaves and tracks applications, providing a round groove rolling surface for guided movement.
The SHEAVE, BALL BEARING description means the wheel rotates on ball bearings, which reduces friction at the pivot so doors or panels move more smoothly along their track.
The Web Description specifies Use #4 Flat Head Wood Screw, so the sheave is intended to be mounted with a #4 flat head wood screw as its pivot point.
Steel finish means the sheave presents a steel running surface, giving a hard metallic contact area for the track that supports regular rolling cycles in builders hardware use.
The round groove design lets the sheave track along a matching rounded surface, helping keep the guided member aligned within sheaves and tracks systems specified for that profile.
Knape and Vogt branding connects the 429 STL sheave to an established builders hardware line, which supports consistent part selection alongside other Knape and Vogt sheaves and tracks.
The 429 Steel Round Groove Sheave from Knape and Vogt combines a ball bearing core, steel finish, and round groove profile defined for builders hardware sheaves and tracks. The Web Description guidance to use a #4 Flat Head Wood Screw ties the wheel to a clear mounting method. For projects that need a compact open wheel sheave with a known brand and part number, this 429 STL sheave provides a straightforward choice when planning or updating track-based movement.
