SPK Lofting Stapler
Attach glazing cassettes to their parent frame for spray finishing. No clamps. No tape. Just a foot pedal.
Why Choose the Copenstick SPK Lofting Stapler?
Spray finishing glazing cassettes attached to their parent frame has always presented a handling challenge. Without a reliable temporary fixing, cassettes shift during the finishing process, leading to uneven coverage and re-work.
The SPK Cassette Lofting Station solves this with a purpose-built pneumatic station that fires a single angled fixing into each corner of the cassette back face. The fixing is driven at a set angle so it extends fractionally past the outer perimeter of the cassette, creating just enough friction to hold the cassette firmly against the frame throughout the spray finishing process. When painting is complete, the fixings are removed and the cassette separates cleanly.
It is a controlled, repeatable process that keeps cassettes exactly where they need to be, every time.
Corner-Located Accuracy Each corner is placed into the guide plate with the front face against the plate, ensuring consistent positioning before the fixing is driven.
Foot-Pedal Operation One tap of the pedal fires the fixing. Both hands remain free to hold and position the workpiece safely.
Angled Fixing for Positive Friction The nail is driven at a set angle so it extends just past the cassette perimeter, creating the friction needed to hold the cassette in place without damaging the frame or face.
Clean Release After Finishing Once the spray process is complete, fixings are removed and the cassette separates with minimal touch-up required.
Mobile and Workshop-Ready Mounted on castors with levelling feet, the SPK positions where it is needed and stays put during use.
Ideal for: glazing cassette spray finishing lines • timber window production workshops • batch painting of pre-assembled cassettes and frames
How it works
Position the Corner Place the cassette corner into the guide plate of the lofting station with the front face against the plate.
Secure and Fire With the corner held in position, tap the foot pedal. The SPK drives a 38 x 26 mm wide crown staple into the back face at a set angle.
Repeat All Four Corners Work around the cassette, firing one fixing per corner. The angled staples extend fractionally past the cassette perimeter on each side.
Attach to Frame and Finish Press the cassette onto the parent frame. The staple ends grip the frame edge, holding the cassette firmly in place for spray finishing.
Remove and Make Good Once finishing is complete, remove the fixings. The cassette separates cleanly from the frame with only minimal touch-up needed.

Frequently Asked Questions (FAQs)
-
The staple is driven at a set angle so that the legs extend fractionally past the outer perimeter of the cassette. When the cassette is pressed onto the parent frame, these protruding ends create a small amount of friction against the frame edge, holding the cassette securely in position during the spray finishing process.
-
The fixing is driven into the back face of the cassette only, away from any visible surface. The front face rests against the guide plate throughout the process, protecting it entirely. Only the back face and perimeter edge are affected, requiring minimal touch-up on removal.
-
The SPK uses 38 x 26 mm 16g wide crown staples, available from standard fixings suppliers.
-
The SPK accepts workpieces from 10 x 15 mm up to 30 x 80 mm, covering the majority of standard glazing bar cassette profiles.
-
A standard 6 bar compressed air supply. The SPK connects to any workshop airline with a compatible fitting.
-
Yes. The SPK is mounted on castors with built-in levelling feet, so it can be positioned wherever it is needed on the finishing line and locked in place during use.
