What’s Included
Boston Z-Bar French Cleat Hanging Rail, 300mm (11.8″), Pre-Drilled (3 Holes), 40kg (Pack of 1)
Sold individually to allow you to create custom length combinations.
Installation – please read
You can use two rails of the same length to get a perfectly balanced and uniform hold for a standard item. Alternatively, you can use two or more rails of different lengths to securely fit and balance unusual or custom-sized items. This flexible approach makes it easy to secure frames, mirrors, or panels of any size. Rails are offered as singles.
Mix and Match Modular Rail
The Boston Z-Bar system is fully modular, so you can pair different rail lengths to suit any hanging project. Because the interlocking cleat profile remains consistent across the entire range, a longer rail mounted to the wall can easily support a shorter rail attached to your frame—or vice versa. This flexibility lets you buy exact quantities, adjust anchor placement around existing wall studs, and create custom configurations without paying for excess hardware.
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).
Maximum capacity
Weight ratings apply strictly to the structural limit of the aluminium rails. In practice, wall anchors and fixings (screws, wall plugs, masonry anchors) almost always fail before the rail itself. Always ensure your chosen fixings and wall structure are rated to support the total weight of your item.

Here are example images of how the system can be used. Look above for what’s included.
