Intumescent gasket set (2420.IP)

A significant amount of fire resisting doorset material is removed when concealed closers are mortised into the door leaf. The intumescent gasket set will provide the additional performance that is required to protect the door from integrity failure during fire conditions.

It is particularly important with these closers to check that the details of the fire test certification are relevant to your intended door application.


Additional features

Optional cushion stop (ref: 2420.CS) helps prevent doors from coming into contact with adjacent walls (note: this is not a backcheck function).

Optional mechanical hold-open unit can be retrofitted into the slide track. Hold-open angle can be adjusted from 80˚ to 120˚ and allows the door to be

manually released from the hold-open position. Mechanical hold-open must not be used on fire and smoke doors.
