Designed for aluminium or timber framed vents measuring up to 60cm square (2ft square) lifting  a load of up to 6kg (14lbs).


Provides a maximum opening distance of 12 inches (30cm) and can be set to start opening at approx. 55F (12º). Supplied with full fixing kit and instructions. The standard Mk 7 autovent is supplied in a satin anodised finish.

Q. I have a roof window opening of 1.4 x 550 if I buy 2 of these for this size window will they work in unison together. Thanks

A. This can be done. It will just take a few days to a week to get both of the auto-vents sharing the load. I would definitely suggest no alternative for this job - The MK7 is the only real option for this size.

by D Siveter

Prompt delivery, easy to fit.

by Sylvia Broomfield

This was a direct replacement for vent openers which had been installed a long time ago and stopped working. It helped that it was described as Alton (we have had an Alton Amateur for over 30 years) but opener dimensions were not immediately obvious. We knew these were good from previous experience.

Very good service. Arrived next day. My only comment is that it would be good to receive a conformation of your order. Other than that I would recommend your company to all my friends. Regards David Williams.
