Wall collars are ideal for fitting around plastic pipes that are already installed in the wall. Installing one internal wall collar in the cavity of the wall eliminates the need to install two retrofit collars externally ie: one either side of the wall. This also avoids the collar being visible which in certain areas may be more appealing. They provide an efficient and quick method for sealing plastic pipe penetrations through walls. Available in various sizes between 40mm to 150mm (internal diameter).
