The fastest profile clamp to set on external corners
Traditional corner clamps wrap the brickwork — effective, but slower to set and pack up. The nail-on external clamp skips that step entirely: tap a concrete nail into the perp joint or mortar, locate the clamp, and you’re holding the profile. Seconds per setup across a long run adds up to real time saved over a shift.
How it works
- Align the clamp against the external corner
- Tap the included concrete nail through the fixing hole into the perp joint or mortar bed
- Engage the profile — you’re clamped and ready to lay

Works great but could do with 2 more nails in them
G’day Billy,
Thanks for the feedback. Please feel free to put as many nails as you think you need. We only supply two nails as we found that was the most useful to guys onsite.
Brilliant profile clamp just simply nail on into the perp and clamp the profile.
Simple to use either nail into the perps or bed joints to clamp the profile.
Perfect clamps
