turned top rung for library ladders describes a Quiet Glide component designed as a wide-turned rung for rolling library ladders, so it serves as a structural step or handhold within a ladder layout where that exact form is needed. The overall length of 19-3/8 inches sets the clear span this rung can bridge between ladder side members, which helps plan rail spacing when laying out a rolling library ladder. The 20 inch wide-turned description signals a broad turning profile relative to compact ladder parts, supporting use on full-size library ladders. Being part of the Rolling Library Ladders product class links this rung directly to that specific application, which helps match it to existing Quiet Glide ladder designs. Its role under the Ladder Hardware category places it squarely in builders hardware workflows for wood ladder construction.
The unfinished alder construction described for this wide-turned rung means the surface arrives ready for machining and finishing, which lets woodworkers sand, profile, and stain or clear-coat the rung to match adjacent ladder components. Its 7/8 inch turned down ends and 1/2 inch length provide clear geometry for boring and depth stops during ladder assembly, so installers can set up drill presses or jigs around those fixed dimensions. The 1-1/4 inch center diameter guides any additional shaping or slight easing of edges, allowing controlled modification while keeping the main structural dimension intact for library ladder use.
This 20 inch wide-turned rung for Rolling Library Ladders is built specifically for use within the Rolling Library Ladders product class, so it aligns with typical full-height library or bookshelf ladder projects that rely on wide wooden rungs. The overall length of 19-3/8 inches sets it up for ladders where the stiles are spaced to accept that span, which helps produce a uniform ladder width across all steps when repeating the same rung part. Alder as the specified wood species positions this rung for projects where alder is already used for stiles or surrounding trim, so color and grain can be brought into a coordinated finish during final staining. The turned 1-1/4 inch center diameter offers a generous surface for feet or hands on a library ladder, giving the rung a substantial presence that matches the scale of rolling library installations.
The 7/8 inch diameter on the turned down ends of this rung provides a precise drilling target in the ladder stiles, so repeated 7/8 inch bores can be used to create a consistent series of rung sockets. The 1/2 inch length of those turned down ends defines how far each end seats into the stile, allowing predictable shoulder registration that keeps rungs aligned and square during glue-up or mechanical fixing. The 1-1/4 inch center diameter stays larger than the end tenon diameter, which naturally creates a shoulder at each end of the wide-turned section, helping locate the rung flush to the stile face. The stated unfinished alder construction enables sanding and finishing as part of the ladder build sequence, so minor fitting adjustments or edge breaks can be completed before stain or clear finish is applied. Being designated as Quiet Glide Rolling Library Ladders hardware ties this rung to a known library ladder system, which helps installers reference the QG.610-20.AD part number when repeating successful ladder layouts or replacing a rung with the same dimensions.
The rung has an overall length of 19-3/8 inches, a 1-1/4 inch diameter at the center, and 7/8 inch diameter turned down ends that are 1/2 inch long, guiding ladder stile spacing and drilling.
The Quiet Glide rung is made from alder, giving woodworkers a known hardwood species that can be machined and finished to coordinate with alder ladder stiles or trim.
The 7/8 inch turned down ends define the hole diameter needed in ladder stiles, so installers can bore matching sockets for a snug, repeatable mechanical interface at each rung location.
Unfinished alder indicates the rung surface is ready for sanding, staining, or clear coating, allowing ladder builders to match the rung finish to surrounding alder wood components.
The 1-1/4 inch center diameter creates a substantial wide-turned surface, providing a solid area for footing or gripping on a library ladder while maintaining the specified rung geometry.
Part number QG.610-20.AD identifies this specific 20 inch wide-turned alder rung, helping professionals reorder or specify the exact same ladder component across multiple projects.
This 1-1/4 inch x 19-3/8 inch wide-turned top rung for library ladders combines a 20 inch wide-turned alder body with 7/8 inch by 1/2 inch turned down ends, giving a defined interface for Rolling Library Ladders projects. The Quiet Glide QG.610-20.AD part number anchors it within the Rolling Library Ladders hardware range, so recurring work can standardize around these same rung dimensions. For ladder builds or replacements calling for alder, this unfinished wide-turned rung offers a ready-to-finish component that matches the specified geometry and material.
