16 inch top rung unfinished describes a Quiet Glide turned top rung designed for rolling library ladders, so it gives a clear match for ladder projects using this style of hardware. The rung is made from pine, which provides a wood option that can be worked using typical woodworking tools. The overall length is 15-3/8 inches, so it suits ladder designs that are laid out around this specific span between side rails. A 1-1/4 inch diameter at the center creates a consistent gripping surface across the width of the ladder. The ends are turned down to 7/8 inch diameter by 1/2 inch long, creating a stepped profile that interacts with drilled or machined rail holes sized for that interface. The product is part of the Rolling Library Ladders class, so it fits jobs where a rolling ladder system is being built or maintained.
The overall length of 15-3/8 inches defines how far apart ladder rails need to be positioned, so it directly guides layout when building or modifying a rolling library ladder. The 1-1/4 inch center diameter determines the hole or clearance needed around the middle if the ladder design nests the rung within notches or cutouts. Turned down ends at 7/8 inch diameter by 1/2 inch long set the critical end geometry, so rail drilling can be matched to that size for a snug mechanical fit. The pine construction means the rung behaves like other pine components during drilling or shaping, so installers can work it in line with common shop routines.
The product sits in the Rolling Library Ladders class under builders hardware and ladder hardware, so it is intended for rolling library ladder assemblies rather than general step-stool applications. The 16 inch top rung unfinished description ties it specifically to the upper position on a ladder layout, so it is suited for that rung location in a Quiet Glide style system. The Quiet Glide branding and QG.610.PN part number connect it to the same family of library ladder components, so projects that already specify this system can match this rung to other cataloged parts. The 15-3/8 inch overall length allows use in ladder designs that are dimensioned around this span, giving designers a defined working width when planning tall bookcase access.
The 1-1/4 inch diameter at center gives a predictable round cross-section, which helps keep rung feel and spacing uniform when multiple identical rungs are used across the ladder height. Turned down ends of 7/8 inch diameter by 1/2 inch long create a repeatable tenon-like geometry, which supports consistent drilling patterns in the rails and reduces variation from rung to rung. The unfinished pine surface means the part can be finished in the same sequence as the ladder rails, so color and sheen can be matched across the whole assembly once machining is complete. Having a clearly defined QG.610.PN identifier supports repeated builds or future service work, because the same pine top rung can be specified again when a library adds matching ladder runs.
The rung is part of the Rolling Library Ladders product class, so it is intended for use in rolling library ladder assemblies in woodworking projects.
The Quiet Glide rung has an overall length of 15-3/8 inches, so ladder rail spacing can be planned around that fixed span between the sides.
The rung center has a 1-1/4 inch diameter, creating a uniform round profile for gripping and stepping across the width of the ladder.
The turned down ends measure 7/8 inch diameter by 1/2 inch long, so rail holes or mortises can be sized to that dimension for a fitted connection.
The 16 inch top rung is made from pine, allowing it to be worked and finished using common woodworking tools and finishes used on pine components.
The QG.610.PN part number identifies this specific Quiet Glide pine top rung, helping match it within Rolling Library Ladders hardware for repeat projects.
This Quiet Glide 16 inch top rung unfinished combines a 15-3/8 inch overall length, 1-1/4 inch center diameter, and 7/8 inch turned ends, so rolling library ladder projects can be laid out around clear dimensions. The pine construction and defined QG.610.PN identifier support repeatable builds using the same ladder hardware profile.
