High-tensile stainless steel lead flashing clips that fix lead into masonry joints in seconds. V-shaped design grips lead firmly without wedges. Covers joints from 6mm to 18mm. 50 clips per bag.
Hall Clips are stainless steel lead flashing clips designed by a working roofing contractor who had one too many lead wedges drop out at the wrong moment. The result is a V-shaped, high-tensile clip that holds lead flashing firmly in a masonry joint in seconds, without cutting, without hammering, and without the wedge disappearing into the gutter. For anyone fitting lead flashing clips regularly, these are the sort of product you try once and do not go back from.
Each clip handles joints from 6mm to 18mm, which covers the vast majority of brick and stonework on domestic and commercial roofing work. Push the clip into the raked joint, feed the lead flashing behind it, and the V-shape grips the material securely straight away. You can then dress the lead accurately without it pulling away from the wall, which makes for a neater finish and a more reliable point. The manufacturer’s claim of up to 20 times faster than traditional lead wedges is not hard to believe once you have used them on a full run of step flashing.
Why Roofers Choose Hall Clips Over Lead Wedges
The traditional wedge method is slow and fiddly. You cut small lead wedges, tap them in by hand, and hope they stay put while you work along the course. Hall Clips remove that process entirely. The clips remain in the joint permanently, sitting behind the mortar once the job is pointed up, so there is nothing to come loose over time.
Being stainless steel throughout, there is no corrosion risk and no reaction with the lead itself. That matters on a roof expected to last 50 years or more. A bag of 50 is a practical quantity for a day’s flashing work on a standard chimney or abutment. The clips are light enough that a few bags take up almost no space in a tool bag, so there is little reason to ever run short on site.
Pro Tip: Rake out the joint to a consistent depth of around 25mm before fitting Hall Clips so the V-shape has enough material to grip against and the lead sits flush against the wall face.
Hall Clips are used wherever lead flashing needs to be fixed into raked mortar joints on masonry. The most common application is step flashing on chimney stacks, gable abutments, and dormer cheeks, where the lead is dressed into the brick course at regular intervals up the slope. They also work well for horizontal chase flashing where the joint width falls within the 6mm to 18mm range.
Roofers use Hall Clips on new-build roofing, re-roofing, and repair work on domestic and commercial properties. The clips suit any situation where a raked joint in brick or natural stone is present and the joint width is within range.

Not suitable for: Hall Clips are not suitable for joints narrower than 6mm or wider than 18mm. For unusually tight or wide joints, traditional hand-cut lead wedges will still be required.
Rake out the mortar joint to a clean, consistent depth before fitting. Push the Hall Clip firmly into the joint so it seats securely, then slide the lead flashing up behind the clip. The V-shape grips the lead against the masonry and holds it in position while you dress the flashing and work along the course.
Space clips at regular intervals along the joint, typically every two to three brick courses on step flashing. Once all clips are set and the lead is dressed, point up the joint with mortar as normal. The clips remain permanently behind the pointing.
Rake out the masonry joint to a clean depth of approximately 25mm along the full flashing run.
Push a Hall Clip firmly into the joint at your first fixing point, ensuring the V-shape is fully seated.
Slide the edge of the lead flashing up behind the clip so the clip grips the lead against the back of the joint.
Repeat at regular intervals, typically every two to three brick courses for step flashing.
Dress the lead flashing down the roof slope, working along the course with the lead held securely in place.
Point up the joint with mortar once the lead is fully dressed, covering the clips permanently.
Can Hall Clips be used on natural stone as well as brick?
Yes. Hall Clips work in raked joints in natural stone as well as brick and blockwork, provided the joint width is between 6mm and 18mm. The V-shape grips against the sides of the joint rather than relying on a specific material, so stone and brick both hold the clip securely.
Do the clips need to be removed before pointing up?
No. Hall Clips are designed to stay in the joint permanently. Once the lead is dressed and you are satisfied with the position, point up directly over the clips with mortar. The clips sit behind the pointing and are not visible once the job is finished.
Hall Clips are manufactured from high-tensile stainless steel, giving them long-term corrosion resistance in exposed roofing environments. The V-shaped profile is designed to compress slightly on insertion and spring outward against the joint walls, creating a mechanical grip that holds lead flashing without the need for adhesive or additional fixings. The stainless steel construction is inert in contact with lead, avoiding any bimetallic corrosion risk over the lifespan of the flashing.
