AirScape Low Clearance Adapters
AirScape low attic clearance adapters for AirScape Powered AirLock damper boxes. PAL14 adapters are for use with the Sierra 3200 and PAL26 adapters for Sierra 3400 and larger whole house fans. Use when low attic height prevents the duct from being attached directly to the PAL unit.
Note that each adapter is available in a rotated (RLCA) version. They are size specific to the joist/fan orientation and cannot be rotated in the field.
LCA - duct on longer side. RLCA - duct on shorter side.
Powered AirLock damper boxes (PALs) shown in the pictures are NOT included. The low clearance adapters are the sheet metal duct transitions on top of each PAL.
