Rated 5 out of 5 by from Easy to use Relatively inexpensive for a complex plastic moulding. Good value and is adjustable, doing the job of re-directing airflow from airbrick to below a suspended wooden floor after some refurbishment work.

Rated 5 out of 5 by from Solved a problem Used to build an air channel under a floor to an enclosed room. One at each end of a channel with ducting and airbricks, backfilled with concrete. Worked a treat.

Rated 5 out of 5 by from Good product Manthorpe product worked great but would be good if you could also buy the G962 which converts the rectangular opening to accept 100mm round pipe but used 2no 100x50mm channels instead which worked with a bit of adaption! Otherwise vents do the job great. Used to extend vents under subfloor to outside extension wall to vent the existing timber floor.
