We are all familiar with the old Mez Clamp used for clamping large duct sections together.
Introducing another new innovation from Bullock
The TDC/TDF Clamp uses a nylon bolt for connecting duct to fire dampers.
Product Code: #1390 TDC/TDF Corner Clamp with gal bolt
Product Code: #1390/1 TDC/TDF Clamp & 8mm nylon bolt
Ensure you comply with AS1682.2 by maintaining the breakaway connection without air leakage. Should be used in conjunction with nylon bolts and 18×6 foam tape for perfect duct to fire damper connection.
Some companies innovate, some just imitate.
