A stainless steel wall starter kit does one job and does it properly: it ties a new wall into an existing masonry structure without the movement, cracking or settlement that comes from a poorly connected junction. Whether you’re extending a building, adding a partition or building a new leaf onto an existing cavity wall, getting that connection right from the start saves a lot of grief later. This kit uses stainless steel throughout, so there’s no risk of corrosion at the interface between old and new masonry, which matters on external walls in particular.
Each kit contains two 2.4m wall rails, ten wall rail connectors, five plugs, five coach screws and five washers. Everything you need to make a proper structural connection between the new and existing build, without sourcing components separately. The rails sit vertically against the existing wall face, fixed through the plugs and coach screws, and the connectors slide into the rail to engage with the blockwork or brickwork courses as you build up. The connectors can be positioned at any course height, which is a genuine advantage over fixed-position alternatives when your coursing doesn’t line up perfectly with a pre-drilled fixing point.
Where Stainless Steel Wall Starter Kits Are Used
The adjustable connector system means you’re not fighting the coursing. On a standard brick or block wall, the connectors drop into the rail channel and sit tight without any fuss. The stainless steel construction means this kit is equally suited to internal work and fully exposed external situations, where lesser materials would eventually let moisture do its worst.
Specified regularly by structural engineers and site managers on new builds and extensions alike, wall starter kits have largely replaced the older method of stitching in every few courses, which required breaking out and was considerably more disruptive to the existing structure. Using a stainless steel wall starter kit keeps the existing wall intact and gives a cleaner, faster build.
Available in single units or bulk box quantities, making it straightforward to order ahead for larger projects without paying over the odds.
Pro Tip: When fixing the wall rail to the existing masonry, use a level and check plumb before tightening the coach screws, as a rail even slightly off vertical will cause your new wall to drift over several courses.
Wall starter kits are used wherever a new masonry wall needs to be tied into an existing brick or block structure. Common applications include house extensions, internal partition walls built off existing external walls, outbuildings joining onto existing structures, and infill panels within steel or concrete frames. They are used by bricklayers, groundworkers and general builders across residential, commercial and light industrial projects.
The stainless steel construction makes this kit appropriate for external and exposed internal situations where moisture is a consideration, including cavity wall construction and below-DPC applications where corrosion resistance is important.

10 x wall rail connectors
5 x plugs
5 x coach screws
5 x washers
Not suitable for: Not suitable for use with timber stud walls or as a replacement for structural movement joints where differential settlement is expected. Not intended for use in seismic or high-load structural applications without engineer specification.
Fix the wall rail vertically to the face of the existing masonry using the supplied plugs, coach screws and washers. Check plumb carefully before tightening. As you build up the new wall, slide the connectors into the rail channel at the appropriate course height and bed them into the mortar joint. Connectors can be repositioned along the rail to suit any coursing pattern.
The connector spacing should generally follow your engineer's specification or standard practice for the wall type. On standard residential extensions, connectors are typically placed every 450mm vertically, but always confirm with your structural drawings where provided.
Mark the position of the wall rail on the existing masonry face, ensuring it aligns with the intended new wall centre line
Drill fixing holes into the existing masonry at the required centres using an SDS drill and appropriate masonry bit
Insert the supplied plugs into the drilled holes
Offer the wall rail up to the face and fix using the coach screws and washers supplied, checking the rail is plumb before fully tightening
Begin laying the new wall, sliding connectors into the rail channel at the correct height to coincide with mortar bed joints
Bed each connector into the mortar course as the wall is built up, ensuring full contact between connector and mortar
Continue inserting connectors at the specified vertical centres as the wall rises
Check wall alignment regularly as you build and adjust coursing if required before the mortar sets
Can this wall starter kit be used on external walls?
Yes. The stainless steel construction makes it suitable for external use where the connection will be exposed to moisture, including cavity walls and outer leaf applications. Standard mild steel alternatives are not appropriate in these situations.
Do the connectors work with both brick and block coursing?
Yes. Because the connectors slide freely along the rail and can be positioned at any height, they work with standard brick courses, block coursing and most combinations of the two. You're not limited to fixed fixing points, which helps when the coursing of the new and existing walls doesn't line up neatly.
How many kits do I need for a typical extension?
Each kit contains two 2.4m rails, which covers one full-height wall junction up to approximately 2.4m. For a standard single-storey extension with two new wall connections to the existing building, two kits would normally be sufficient, though this depends on wall height and your structural specification.
The wall rails and connectors are manufactured from stainless steel, providing corrosion resistance appropriate for both internal and external masonry applications. The rail profile accepts the connectors at any position along its length, allowing course-by-course adjustment during the build. Fixings supplied are coach screws with corresponding wall plugs and washers sized for standard masonry fixing into brick or blockwork.
