What’s Included in This Pack

METALCITI Boston Z-Bar Rail, 300mm (11.8″), Un-Drilled (No Holes), 40kg (Pack of 1)

Sold as individual rails to allow custom pairing and continuous length runs. Wall plugs, screws, and drill bits are sold separately.

Custom Hole Drilling for Exact Stud Alignment

Because this 300mm rail comes without pre-drilled holes, installers can drill precise fixing points to match wall stud locations, plasterboard anchors, or existing frame fixings, ensuring maximum load distribution without compromised placements.

40kg Heavy-Duty Weight Support

Capable of supporting up to 40kg, this 300mm aluminium cleat provides exceptional strength for heavy timber frames, large glass mirrors, fitted cabinetry, and commercial wall panels. The interlocking Z-profile prevents bowing, sagging, or frame movement.

Ultra-Slim 6mm Flush Wall Profile

With a narrow 6mm depth projection, your mounted artwork or panel sits flush against the wall surface. The interlocking design allows hung items to be lifted off cleanly for maintenance or redecorating without damaging the wall surface.

Installation & Safety Guidelines

Fix one Z-bar rail to the wall with the flange facing upward, and attach the secondary matching Z-bar facing downward on the reverse of your frame or cabinet. Lower the frame onto the wall bracket until the two aluminium profiles interlock fully.

Important Load Information: The 40kg weight rating applies to the structural capacity of the aluminium rail itself. Always select suitable screws and wall plugs for your wall type (e.g., solid masonry vs plasterboard studs) to support the total load safely.

Application Examples

These are just examples of how you could combine the lengths; they are not a list of what you will receive. You can mix and match rails of different lengths as you like, such as one 600mm rail on the wall and three 50mm rails on the item, or a 900mm rail on the wall with a 900mm rail on the item, or a 1200mm rail on the wall and two 300mm rails on the item. The only requirement is that all pieces must be the same profile (e.g., Boston).
