The Flexmaster U.S.A.® model BO4:  we now offer the Rossi (Everlock) 2” Standoff which was created to replace the friction locks on the market with a more reliable positive (absolute) lock. It is fully hand-operational so that there are no tools needed for adjusting or readjusting the damper blade position on site. Rossi products adhere to all UL requirements, Plenum ratings and SMACNA standards for manual damper and comply with NFPA 90A & 90B.
