The DURASECURE DD Trap door is the result of Promat’s relationship and commitment to specific client development to meet a unique performance specification for security and fire rated trap doors. Incorporating a heavy duty leaf with a 3-way shoot bolt mechanism and pin hinge, the doorset offers an enhanced level of security, up to British Telecom test standards. The trap doors are designed to withstand medium traffic loads and can be set up to provide assisted opening for panic escape situations.
