Zinterlock: your secure mounting solution

Zinterlock Split Batten Hanger Bracket

Hang any heavy item safely & rigidly, on any wall
Perfect for panels, art works, cabinets, displays
Invisible, near-flush mount (13 mm separation)
Safety Lock prevents removal or accidental lifting
Non-corroding, tough & resilient
Rapid, simple installation

Zinterlock provides a simple and secure method for flush-mounting signs, panels, displays, mirrors, cabinets and other large objects on flat surfaces. Zinterlock’s strong aluminium extrusions fit together to form a “split batten” which can support large or heavy objects indoors or outdoors.  Zinterlock remains hidden from view, while enabling the object to be flush mounted onto the backing surface. A safety rod pins the battens together, ensuring that the object cannot be lifted from its mount.

How Zinterlock works:

Zinterlock consists of two interlocking z-brackets (“split battens”), plus a safety pin to secure the arrangement. Zinterlock can allow lateral adjustment, making installations easier and enabling the object to be secured by sliding sideways onto the locking pin.  Zinterlock is made from non-corroding aluminium alloy, so it can be used indoors or outdoors on all surfaces for a safe, durable mount. . Zinterlock brackets can be easily cut or drilled to your requirements.

Zinterlock’s split batten hanger design is an improvement on the traditional french cleat design.  Split battens are also known as french cleats, metal french cleats, french cleat hangers, cleat hangers, hanger clips, wall hangers, z clips, hook battens, frog cleats, wall panel fixing systems, panel fixings, panel fix, wall board fixings.

Zinterlock Options:

You can buy Zinterlock as packaged, complete sets of short brackets, or in lengths of the Zinterlock extrusion.  See the BUY NOW tab below to order on line, or call us on 0800 200 121.

The sets consist of two matching lengths of Zinterlock, plus a lockpin.  Sets are available in 40mm, 150mm and 300mm lengths.

If you choose to buy the Zinterlock extrusion, we can supply this in 800mm or 2m lengths.  Remember that it takes two pieces of Zinterlock to make a split batten bracket!  The same extrusion is used for the upper and lower part of the split batten combination, and you can cut the extrusion yourself to make the two pieces if you prefer.  Also, you will need to order the locking pin(s) separately from us if you need this.

It takes two pieces of Zinterlock to make up a split batten bracket.  Attach one piece of Zinterlock to the flat mounting surface (eg wall, post etc), using an appropriate fastener (not included).  Note that your choice of fastener depends on the wall material, and the weight of the furnishing.

Attach the other piece of Zinterlock to the back of the furnishing (sign, art work, mirror, cabinet etc) in an inverted position.  You might use an adhesive, or a mechanical fastening (again, not included).

Once the two brackets are in place, simply slide one into the other for a hidden mount. Finally, apply the locking pin between the two to secure the arrangement.

For best results, Zinterlock brackets should span at least 3/4 the width of a suspended furnishing. For large objects, top and bottom pairs may be necessary in order to achieve a consistent offset from the wall. If a flush mount is required (no off-set or gap visible), either the object or the wall should be recessed around the bracket locations to accommodate the thickness of the installed brackets.

Zinterlock’s strong aluminum alloy has impressive weight bearing capabilities: a single pair can easily support several hundred kg.  Careful consideration should be given to how brackets are attached to the suspended object and to the surface being worked with.  Appropriate fasteners might include screws, adhesives, wall anchors, or a combination of these.

Overall thickness when assembled: 13mm (this is the distance separating the item being mounted, from the mounting surface)

Overall width when assembled: 114mm

Overlap: 37mm (this is the extent to which the two battens slide over each other until they mate)



Zinterlock is extruded from Aluminium Alloy 6063/Temper T5.  The product complies with British Standard GB5237-2008.


Zinterlock’s section has an area moment of inertia Ixx about its longitudinal axis of 131.028mm4.

Based on yield strength of 110MPA, maximum distributed load at yield under bending is 12.3kN/m.   In practice, the most likely failure modality for an implementation will be due to vertical shear load at fastening locations where localised material yield using an 8mm diameter fastener is calculated at 2.5kN per fastening.

It is recommended that shear load per fastener should always be lower than 500N (equivalent to a 50kg weight) and in any case should be compliant with relevant specifications for the fastener.  Add fasteners along Zinterlock’s length to distribute load.
