Expansion Gap Spacers

Expansion Gap Spacer

 

Expansion gap spacers will come fitted to Bullock fire dampers to ensure the damper is centred within the penetration, they will not sag like other insulated products leading to gaps above the damper over time.

 

They do not completely encapsulate the damper making installation easy even in the ugliest hole. Tested to AS1530.4, Patent number 726578
