Lambro 106R Aluminium Wall Cap
The Lambro 106R is a new aluminium wall cap measuring 3.25 in. by 10 in. It suits homeowners or contractors finishing an exterior vent opening on a residential or light-commercial building. The durable aluminium construction resists corrosion while the integrated damper blocks wind, rain and pests when the duct is idle.
Spring-Loaded Damper Installation
Mount the cap over the duct opening with screws or rivets appropriate to the wall material; the unit ships without fasteners. The spring-loaded damper closes automatically, so no wiring or adjustment is required. A common issue is forgetting to clear insulation or debris from the damper hinge line, which can stop the flap sealing fully.
Pre-Order Compatibility Check
Verify that the duct termination matches the 3.25 in. by 10 in. opening before ordering. Confirm the wall thickness allows the cap flange to sit flush and that local code permits an aluminium wall termination for the intended exhaust or intake application.

Questions about this item
How can I confirm the spring-loaded damper is operating correctly after installing the 106R wall cap?
After installation, run the connected exhaust fan and observe the damper; it should open fully while air flows and snap shut again when the fan stops, indicating the spring mechanism is working as intended.
What components come with the 106R aluminum wall cap and what additional items are needed for mounting?
The package includes the aluminum wall cap with its integrated spring-loaded damper; mounting screws, duct tape, or sealant for attaching the 3.25 in. x 10 in. opening to your ductwork must be purchased separately.
Which size of the 106R wall cap should I select for a 3.25 by 10 inch duct opening?
The 106R model is manufactured in a single 3.25 in. x 10 in. size, so choose this version when your duct dimensions match those exact measurements.
