BAR Astragal Stapler
Secure half-lap joints and fix plant-on bars to perimeter mouldings. Stainless steel staples available for lasting weather resistance.
Why Choose the Copenstick BAR Astragal Stapler?
When assembling glazing cassettes, holding half-lap joints together during build and fixing end-scribing bars to perimeter mouldings and beads are two of the most repetitive fastening tasks in the workshop. Both demand a reliable, fast fixing that will not compromise the finished joint or the appearance of the assembly.
The BAR stapler is purpose-suited to both operations. Pneumatically powered and available with staples in a choice of three lengths, it drives fixings cleanly and consistently across the full range of standard glazing bar profiles. Stainless steel staples are available, which is an important consideration for window and door manufacturing where long-term corrosion resistance is essential.
At 0.5 kg, it is light enough to use throughout a production shift without fatigue, and connects directly to a standard 6 bar workshop air supply.
Half-Lap Joint Assembly Holds half-lap joints securely during cassette build, keeping bars correctly located while the assembly is completed.
Plant-On Bar Fixing Drives fixings through end-scribing bars into perimeter mouldings and beads cleanly and repeatably, with no secondary operation required.
Three Staple Lengths Compatible with 8 mm, 10 mm and 13 mm staples, giving the flexibility to match the fixing to the profile depth and application.
Stainless Steel Staples Available Stainless steel is recommended for window and door manufacturing, where moisture resistance is a long-term requirement.
Lightweight Pneumatic Tool At 0.5 kg and running on a standard 6 bar air supply, the BAR is quick to pick up, easy to manoeuvre, and straightforward to use across a full shift.
Ideal for: glazing cassette half-lap assembly • plant-on bar fixing to casement and sash mouldings • perimeter bead and moulding attachment • timber window and door manufacturing
How it works
Connect Air Supply Attach the BAR to your 6 bar compressed air line.
Load the Correct Staple Select 8 mm, 10 mm or 13 mm staples to suit the profile and application. Stainless steel staples are recommended for all window and door work.
Position and Fire Place the nose of the tool at the fixing point and pull the trigger. The staple is driven cleanly into the joint or moulding in a single action.
Across the Assembly Work along the cassette or moulding, firing fixings at the required intervals until the assembly is complete.

Frequently Asked Questions (FAQs)
-
Timber windows and doors are exposed to moisture over their working life. Standard staples can corrode over time, which may affect joint integrity and cause staining. Stainless steel staples resist corrosion, making them the appropriate choice for any application where long-term performance matters.
-
The right staple length depends on the profile depth and the application. As a general guide, shorter staples suit lighter mouldings and bead fixing, while longer staples provide more holding strength for half-lap joints in heavier profiles. If you are unsure, our team can advise on the correct specification for your profiles.
-
Yes. The BAR is suited to both operations. The choice of staple length allows you to match the fixing to the task, whether you are holding a half-lap joint during cassette assembly or attaching an end-scribing bar to a perimeter moulding.
-
