Infinex aluminum square extrusion 72 inch black is a 72 inch black aluminum square profile from Tresco Lighting that forms the structural channel for a custom LED fixture. This extrusion is part of the Infinex LED aluminum extrusion system, so it works as one component within a matched set of Tresco lighting parts on a job. The square profile gives a straight, defined channel for the LED run, which helps maintain a consistent layout along cabinets or casework. Because the system is aluminum, the extrusion provides a rigid track for LED components during installation. The 72 inch length offers a long, continuous run to work across wider cabinet sections or combined segments, supporting layout flexibility. As an LED lighting accessory, this extrusion focuses on providing the physical housing needed so the light lines up cleanly with surrounding woodworking.
The Infinex system supports surface mounting of the assembled light using magnets, U-Clips, or screws, so the extrusion is designed to accept these mounting approaches in typical woodworking installations. Magnets can slide into the channel on the bottom of the light, which means the extrusion channel geometry is arranged to hold those magnets in position for mounting to a metal-friendly surface. Having options for magnets, U-Clips, or screws gives flexibility when planning how the finished LED run attaches to cabinets, displays, or other surfaces on a project. Because this extrusion is part of that system, its shape and channel form contribute directly to how securely the finished fixture will mount once the LED components are in place.
This Infinex aluminum square extrusion 72 inch black sits within a broader Tresco Infinex LED aluminum extrusion system, so it is intended to be used where a coordinated Tresco lighting layout is planned. The square profile works as a defined channel when a straight, squared lighting line is preferred along cabinetry or casework edges. Because Infinex is built around choosing a style, cutting to desired length, and assembling, this 72 inch piece can be cut into one or several segments to match the exact run lengths across a project. Being an LED lighting accessory places this extrusion in the role of physical support for LED components, which is important when the finished line of light must track accurately along a face frame, underside, or interior span.
The system is noted as having five profiles with an array of installation options, so this square version fills the need where the geometry of a square channel better matches the look or mounting surface. The black finish indicated in the product name visually ties this extrusion to darker casework or shadowed mounting locations, which can help the hardware recede visually while the LED output remains prominent after assembly.
The Infinex description highlights that gone are the days of set fixture sizes, because the installer chooses the style, cuts to the desired length, and assembles, so this 72 inch extrusion functions as flexible stock that can be tailored for repeatable layouts across multiple cabinets. The ability to cut the extrusion to length allows consistent spacing and alignment from job to job when the same measurements are used. Infinex works with all Tresco 12VDC power supplies, so this extrusion participates in a system where the power side is standardized around Tresco 12VDC, helping keep the lighting layout consistent within that voltage ecosystem.
The note that Tresco fixtures are designed to operate only with genuine Tresco transformers, power cables, connecting cables, and switches shows that this extrusion is intended to be part of a single-manufacturer system, which can simplify planning when every component is chosen from the same Tresco catalog. As a Tresco Lighting product, identified by manufacturer part number L-XSQR72-BL-1, it ties directly to that system for reordering or matching on repeat projects. The statement that it is recommended to use Tresco items together emphasizes that the extrusion has been specified alongside those components for coordinated performance in the intended LED assemblies.
This product is an Infinex aluminum square extrusion, 72 inch, black, from Tresco Lighting, serving as an LED lighting accessory that forms the structural channel for customized LED fixtures.
The Infinex system supports surface mounting using magnets, U-Clips, or screws, so this square extrusion participates in installations using those mounting methods on suitable surfaces.
The Infinex system is described as choose your style, cut to desired length, and assemble, so this 72 inch extrusion is meant to be cut to the lengths needed for a particular run.
The Infinex system works with all Tresco 12VDC power supplies, so layouts built around this extrusion are designed to operate within Tresco 12VDC power configurations.
Magnets slide into the channel on the bottom of the light in the Infinex system, so the extrusion channel supports magnet placement for surface mounting where magnetic attachment is useful.
Tresco fixtures are designed to operate only with genuine Tresco transformers, power cables, connecting cables, and switches, so this extrusion is positioned as part of that coordinated Tresco system.
This Infinex aluminum square extrusion 72 inch black provides a 72 inch black aluminum square channel within the Tresco lighting system, so it supports projects that rely on cut-to-length LED fixtures built from matched Tresco components. The surface mounting options using magnets, U-Clips, or screws give flexibility when laying out lighting across differing cabinet or display surfaces. Because Infinex works with all Tresco 12VDC power supplies and is intended to operate with genuine Tresco transformers, power cables, connecting cables, and switches, choosing this L-XSQR72-BL-1 extrusion keeps the LED housing aligned with that unified Tresco 12VDC approach on professional and serious DIY lighting installations.
