Boost Me

The original joiner/coupler for Irwin Heavy Duty clamps doesn't seem to be available anymore, so I designed replacement.

This coupler allows you to connect two clamps together, instantly increasing your clamping capacity for larger glue-ups.

Perfect for when one clamp just isn’t long enough.

Tested on Irwin Heavy Duty clamps for a secure fit and reliable alignment.

Extend your clamps instead of buying longer ones
Bring old or incomplete clamps back into use
Ideal for large panels, frames, and wide assemblies
Designed for Irwin Heavy Duty clamps (not medium duty)

PRINT IN PETG MINIMUM.

Tested with PLA, ABS and PETG. PETG by far the best.

HARDWARE NEEDED

2x M6 bolts
2x washers
2x knurled thumb nuts
