Window Hardware for Aluminium & uPVC

Handles, friction stays and hardware for aluminium and uPVC windows, alongside professional applicator guns for one- and two-component sealants and adhesives.

Single and multi point locking handle systems

Alualpha handles are made for aluminium windows and come with a 5-year guarantee, so fabricators and installers know what they’re getting. You’ll find single-point locking for straightforward jobs and multi-point locking where more security is needed, from a basic casement window right up to higher-security setups.

It’s not just the handles either. The range includes the corner transmission units and striker/adjustable plug components that go with them, so you can get a complete locking mechanism from one supplier instead of chasing parts from different places.

Stainless steel friction stays for top-hung and side-hung windows

Securistyle friction stays hold a sash open at any angle and close it smoothly and square against the frame. They are made from stainless steel and come with a 10-year guarantee, so fabricators and installers know the stay will keep its grip long after the window is fitted. The stays are tested to 30,000 opening cycles.

It’s not just about the stay itself either. The right stay depends on the sash weight and size, so we help you match the length and load rating to your window instead of guessing from a catalogue. They suit aluminium, uPVC and timber frames, so one supplier can cover the whole job.

Precision dispensing systems for sealants & adhesives

The gun matters just as much as what’s in the cartridge. This range covers all three drive types: manual guns for smaller jobs and tighter budgets, pneumatic guns for high-volume site or workshop work, and cordless guns for when mobility matters more than an air line.

Every gun in the range handles both one-component (single cartridge) and two-component (dual cartridge) sealants and adhesives, so you can match the right gun to whichever Dowsil, structural or panel-fixing product the job needs. That means more consistent application and less wastage than manual mixing or makeshift tools.

Manual Applicator

Hand-held guns for cartridges and sausages: precise, portable, and site-ready.

Pneumatic Applicator

Air-powered dispensing for cartridges and sausages on high volume glazing lines.

Cordless Applicator

Battery-operated guns for cartridges and sausages, giving you consistent beads without the fatigue of manual pumping.

Why it matters

Hardware you don't have to think about twice

A window gets opened and closed thousands of times over its working life, and every one of those cycles puts load on a handle, a hinge or a stay. Cheap hardware tends to fail quietly at first, a handle that needs a firmer push, a stay that drops a few degrees from where it’s set, long before it fails outright. By the time a callback comes in, the window has usually been working harder than it should for months.

Matched to the frame material

Aluminium and uPVC windows don’t take hardware the same way. Alualpha and Securistyle are built around aluminium profiles, while Pulse rounds out coverage for uPVC, so the fitting is matched to the frame rather than forced to fit.

Backed by real guarantees

A 5-year guarantee on handles and a 10-year guarantee on friction stays aren’t marketing numbers. They reflect how long the manufacturer expects the mechanism to hold under normal daily use, which is a useful benchmark when comparing against unbranded alternatives.

One supplier for hardware and tools

Because we stock the applicator guns alongside the hardware, a fabricator or installer can source the fittings and the tools to seal around them from a single branch, rather than chasing down a gun supplier separately.
