Manrose DHRIWKBBS Deluxe Quick Internal Fit Adjustable Wall Kit With Brown External Grille, Rubber Seal & Backdraught Shutter Wall Thickness: 225mm - 390mm | Hole DiaØ: 117mm

Manrose DHRIWKBBS Description

The Manrose Deluxe DHRIWKBBS is an adjustable wall kit with brown external grille, backdraught shutter and rubber seal that can be used with any 100mm fan.

Designed to simplify installation by allowing the user to fully fit inside the building, avoiding the need for scaffolding and significantly reducing the cost and complexity associated with working from heights.

The innovative new wall kit includes an adjustable wall liner and external grille with backdraught shutter and a rubber seal on the outside of the building. The rubber seal is protected against water ingress, which makes the deluxe wall kits ideal for use in areas that experience a lot of moisture build up.

The wall kit can be adjusted to wall thicknesses anywhere between 225mm and 390mm - just measure the wall, then use the guide on the tube of the wall kit to set it to the correct length. The external grille and seal can then be pulled back against the external wall so a tight fit can be achieved. 

The external rubber seal covers up any break out on the external hole and leaves a clean, tidy finish.

The wall kit is also suitable as a passive air inlet grille
