20 inch wide-turned ladder rung describes a Quiet Glide top rung sized for rolling library ladders, so installers get a purpose-built component for building or repairing this style of ladder. The unfinished hickory construction gives a solid wood rung that can be finished to match surrounding millwork. With an overall length of 19-3/8 inches, the rung is proportioned for common library ladder widths while leaving clearance at each side in typical rail layouts. The 1-1/4 inch diameter at the center creates a rounded gripping surface that supports confident footing and hand placement on the ladder. Turned down ends at 7/8 inch diameter by 1/2 inch long reduce the end profile, which helps the rung seat into appropriately sized side members or brackets. As a top-turned rung, it fits into the upper position of the ladder, where consistent diameter and length support straight, even ladder alignment.
The overall 19-3/8 inch length of this top-turned rung provides a fixed dimension for setting rail-to-rail spacing on rolling library ladders, which keeps the ladder body square to the track. With a 1-1/4 inch center diameter, the rung defines the depth of the step surface, which informs spacing between rungs so movement feels consistent from one rung to the next. The 7/8 inch diameter by 1/2 inch long turned down ends establish the interface into side rails, so rail drilling or boring can follow those measurements for a snug, repeatable fit. Because the rung is specified as a top-turned component, its dimensions help set the starting reference at the ladder top, which can be carried down through all remaining rung locations.
This 20 inch wide-turned rung is identified for rolling library ladders within the builders hardware and ladder hardware categories, so it suits projects where a movable ladder travels along a rail. Its role as a top-turned rung places it at or near the upper portion of the ladder frame, where consistent diameter and straightness support smooth engagement with the rail hardware. The 19-3/8 inch overall length works in ladder designs sized around that span, giving a known cross-member dimension when laying out side rails. Because the rung is made from unfinished hickory, it aligns well with installations that feature exposed wood ladders and bookshelves, allowing the ladder to visually coordinate with hickory casework or trim.
The 1-1/4 inch diameter at the center of the rung establishes a uniform profile for stepping and gripping, which helps keep ladder use consistent when multiple rungs share the same size. Turned down ends at 7/8 inch diameter by 1/2 inch long create a defined shoulder, giving a positive stop when seating the rung into matching side-rail holes. That shoulder helps maintain alignment from side to side, which supports a square ladder frame that tracks properly on rolling hardware. The precise overall length of 19-3/8 inches provides a dimension that can be repeated across a full set of rungs, reducing layout variation during fabrication. As a Quiet Glide component marked with part number QG.610-20.HC, the rung can be referenced accurately in project documents, simplifying reorders or future ladder modifications that rely on consistent dimensions.
This rung is specified for rolling library ladders in the builders hardware and ladder hardware categories, so it serves as a component in that style of movable library ladder.
The rung has an overall length of 19-3/8 inches, which defines the span between ladder side rails and supports consistent ladder width in that dimension.
The rung center measures 1-1/4 inches in diameter, creating a rounded stepping and gripping surface that matches other components built around that dimension.
The turned down ends are 7/8 inch in diameter by 1/2 inch long, forming reduced sections that fit into appropriately sized side-rail bores or brackets.
The rung is made from unfinished hickory, so it can be sanded and coated to coordinate with surrounding hickory millwork or other specified wood finishes.
Part number QG.610-20.HC identifies this specific 20 inch wide-turned, unfinished hickory top rung, which supports accurate specification and future reordering.
The 20 inch wide-turned hickory top rung combines a 19-3/8 inch overall length, 1-1/4 inch center diameter, and 7/8 inch by 1/2 inch turned down ends, giving installers fixed dimensions for building or servicing rolling library ladders around Quiet Glide components.
