The maximum opening for these 1200mm / 48" sash clamps is approximately 1090mm.
While constructed from strong cast iron, these clamps are primarily designed for woodworking. For metalworking, specific metal clamps offering higher rigidity and heat resistance are typically recommended.
The 55mm x 55mm jaws provide a good surface area. For very delicate finishes, consider using temporary pads made of scrap wood, hardboard, or felt between the clamp jaws and your workpiece.
The chained pin allows you to quickly set the approximate length of the clamp by sliding the jaw along the bar and securing it in one of the pre-drilled holes. This is faster than fully engaging a screw mechanism for initial positioning.
Store them in a dry place. Due to their length, consider wall-mounted racks or storing them horizontally on a shelf where they won't be a tripping hazard.
This specific listing is for a pack of 6 sash clamps.
Ensure the chained pin is fully engaged in one of the bar's holes. Check the pin and the holes for debris or damage.
Clean any dried glue or debris from the acme thread. Apply a light lubricant like paste wax to the thread and work the handle back and forth.
Ensure the acme thread is fully engaged. Check that the jaws are clean and provide good grip. For maximum pressure, ensure the T-bar handle is positioned for optimal leverage.
Lightly sand the rust spots with fine-grit sandpaper or steel wool. Clean the area and apply a thin coat of paste wax to prevent recurrence.
Setup: To set the clamp, slide the movable jaw along the bar to your approximate desired length. Secure the jaw by inserting the chained pin through one of the pre-drilled holes in the bar. For final tightening, slide the clamp into position and rotate the T-bar handle to advance the acme screw, applying firm pressure.
Compatibility: These clamps are designed for general woodworking and assembly tasks. They are compatible with most common wood glues and adhesives. Ensure the surfaces being clamped are clean to prevent contamination of the workpiece or the clamp jaws.
Care: To maintain optimal performance and longevity:
