Sliding Door Track Assembly No. 1 is an EPCO aluminum sliding door hardware set designed for heavier 1/4 inch thick wood or glass doors, so it handles doors in that thickness range used in cabinets or casework. The 3 foot long aluminum track length suits shorter sliding runs where a compact but continuous track is needed. The clear anodized aluminum construction matches the SAP description of an ALU track kit, providing a consistent metal look that coordinates with typical builders hardware. The assembly is part of EPCO Sliding Door Hardware, which keeps the components aligned for this style of sliding application. The kit designation as No. 1, with manufacturer part number 1-A-3, identifies this specific track and guide combination for repeat ordering or matching to project specifications.
This EPCO Sliding Door Track Assembly No. 1 is specified for heavier 1/4 inch thick wood or glass doors, so door edges are expected to match that thickness where they engage the track system. The 3 FT long aluminum track section sets the available sliding distance, which shapes the maximum opening width that can be spanned with this single piece. The clear anodized aluminum construction, referenced as ALU in the SAP description, supports straightforward alignment with other aluminum sliding door components in a build. The 1-A-3 manufacturer part number links the track assembly to a defined configuration, helping keep the same layout when repeating a detail across multiple units.
The web description notes this EPCO aluminum assembly is for heavier 1/4 inch thick wood or glass doors, so the system is intended for doors built from those materials at that thickness. This focus on 1/4 inch door thickness supports use in cabinet, furniture, or light architectural sliding panels that follow that dimension. The 3 FT long aluminum track length concentrates the application on openings that match that span, allowing straightforward placement over narrower casework or built-ins. The builders hardware and sliding door hardware classification aligns the product with jobs where a door must travel along a fixed path while staying guided at top and bottom. In practice, pairing heavier 1/4 inch panels with a dedicated sliding door hardware assembly helps keep door movement aligned with the track profile.
The SAP description explains that this aluminum 3 FT long assembly has an upper guide identified as #48A14-A, a track identified as #38AS14-A, and screws referenced in the description. The web description further specifies that the bottom track has machined, hardened fiber inserts, so the contact path in the lower channel is formed by these inserts rather than bare aluminum. The use of machined inserts creates a defined running surface for the edge interface, which supports smoother, more predictable travel along the bottom track over the 3 FT span. The hardened fiber material in the inserts provides a shaped bearing area that can influence how the door edge rides in the track, adding a purpose-built contact strip instead of a raw metal channel.
The Sliding Door Track Assembly No. 1 is described for heavier 1/4 inch thick wood or glass doors, so it is intended for applications using doors at that 1/4 inch thickness.
The EPCO assembly uses an aluminum track that is 3 FT long, which suits sliding door runs that match this span on cabinets or similar installations.
The aluminum 3 FT assembly is described with an Upper Guide #48A14-A, a Track #38AS14-A, and screws, so these elements form the guided sliding path.
The bottom track has machined, hardened fiber inserts, giving the door a defined running surface, which shapes how the door edge travels along the lower channel.
The assembly is an EPCO product with manufacturer part number 1-A-3, which identifies this specific Sliding Door Track Assembly No. 1 configuration.
The product is categorized as Builders Hardware and Sliding Door Hardware, which places it within sliding door motion systems for planning cabinet or casework layouts.
The EPCO Sliding Door Track Assembly No. 1, with its 3 FT long clear anodized aluminum track, is specified for heavier 1/4 inch thick wood or glass doors, tying the hardware directly to that door profile. With identified parts such as Upper Guide #48A14-A, Track #38AS14-A, and a bottom track using machined, hardened fiber inserts, the assembly delivers a defined top and bottom guiding path. When a project calls for a sliding solution that matches this thickness, material, and length, this 1-A-3 assembly offers a clearly described configuration for consistent planning.
