Top rung maple unfinished describes a turned top rung for library ladders that uses maple and arrives without a finish, which lets installers stain or coat it to match existing millwork or custom ladder projects on site. The overall length of 15-3/8 inches defines the span of the rung, so ladder side rails can be laid out and drilled accurately around this fixed dimension. A center diameter of 1-1/4 inches creates a substantial handhold area that can feel solid during use while maintaining a familiar round ladder profile. The maple species indicated in the description establishes a hardwood rung material, which supports typical interior rolling library ladder applications where wood parts need to machine cleanly. The unfinished status also means surface prep, edge easing, and final finishing can follow the same shop workflow as other maple components in the ladder assembly.
The overall length of 15-3/8 inches defines the distance between ladder rails that this top rung is designed to span, which allows rail layout to be planned around that fixed width. A center diameter of 1-1/4 inches establishes the main cylindrical profile, so drilling jigs and sanding blocks can be sized to that dimension during fabrication. Turned down ends at 7/8 inch diameter across the 15-3/8 inch length create reduced sections suitable for seating into holes or support elements sized to that diameter. Because the description specifies an unfinished maple rung, the piece can be dry-fit first and then removed for sanding and finishing before final assembly into the ladder structure.
This Quiet Glide top rung, designated for rolling library ladders in the product class, is intended for use at the upper position of a wood library ladder assembly. The 15-3/8 inch overall length sets it up as a cross member between two side rails, so projects that follow this width can integrate it cleanly into new builds or ladder upgrades. The 1-1/4 inch center diameter supplies a rounded central section that suits a handhold or standing interface at the top rung, which can matter when the ladder is positioned along tall shelving runs. Turned down ends at 7/8 inch diameter allow this component to sit in properly sized bores or brackets in the rails, which supports a concealed joinery look when side rails are drilled to match that measurement. The maple construction noted in the description means it naturally works alongside maple rails or trim, which is common in built-in libraries and casework.
The clearly stated 15-3/8 inch overall length helps installers cut and bore side rails to a consistent spacing, which promotes repeatable builds when several ladders share the same design. A defined 1-1/4 inch center diameter gives a uniform section for sanding, rounding edges, or applying finish, which keeps the tactile feel the same across multiple ladders using this part. The 7/8 inch turned down ends, running the full length of the rung, provide a constant reduced diameter that simplifies jig-based drilling since rail holes can be sized directly to that figure. The unfinished maple surface allows the same finishing schedule to be applied across the rung, rails, and surrounding maple cabinetry, which maintains visual continuity from the ladder to the casework. The QG.610.MA manufacturer part number ties this rung to the Quiet Glide rolling library ladder line, which aids in reordering matching components so future ladders or replacements follow the same dimensions and appearance.
The top rung has an overall length of 15-3/8 inches, with a 1-1/4 inch diameter at the center and 7/8 inch diameter turned down ends, which sets critical sizing for rail layout and boring.
The 15-3/8 inch overall length determines the spacing between ladder side rails, guiding rail cutting and hole placement so the rung spans correctly across the ladder width.
The unfinished maple top rung arrives ready for sanding and custom finishing, so shops can match stains, paints, or clear coats to surrounding maple cabinetry or trim work.
The 7/8 inch diameter turned down ends create uniform reduced sections that seat into 7/8 inch bores or supports in the ladder rails, helping align and secure the rung mechanically.
This component serves as the top rung in a rolling library ladder, acting as a structural cross member that ties the rails together while providing a 1-1/4 inch diameter gripping surface.
The QG.610.MA designation identifies this specific Quiet Glide maple top rung, making it easier to match dimensions and appearance when ordering parts for new ladders or replacements.
The maple construction, unfinished status, and defined dimensions of this Quiet Glide QG.610.MA top rung create a consistent starting point for library ladder builds where 15-3/8 inch cross members are required. The 1-1/4 inch center diameter and 7/8 inch turned down ends translate directly into drilling and sanding setups in the shop, which supports efficient fabrication runs. For rolling library ladders that rely on matching wood components, choosing this top rung allows the ladder structure to follow a known Quiet Glide dimension set from the first layout through final finishing.
