I just needed the flat rubber bezel to go on the flue (to finish off the installation and hide the messy brickwork). It was easy to cut off the flanges with a sharp knife, and the flat rubber part slid staight over the flue pipe.
firm core and flexible inside and out, used on an odd shaped hole, made a cut at the back out of sight, fitted neatly
Snug fit, just push it in, nothing else to do. Quite pricey though compared to using mortar
Extremely easy to use especially with the 152mm hole saw and a little butyl on a flat roof
Very tight fit for flues. Does the job well
Did just what I needed it for. Sliced it down one side to get it onto the pipe and done.
Had to cut down center to fit around flue pipe then pushed into place, applied a silicone sealant around the lip. Looks great now fitted
easy to install i cut one side to put it around an existing flue and it sealed completely used on the inside as we had a draught no more draught would highly recommend it was a cheap fix with a professional finish would buy again
Be careful it is supposed to be for a 100mm flue but it fits a hold about 152mm in diameter. Looks good quality, but no good for my bore hole.
I purchased this collar to go over a flue terminal the normal collar were too tight as these are designed to fit on when the flue is first fitted. As it's a large size and the hole was only just bigger that the flue i used sand cement on the then I cut the flange off of the body and used the flange it fitted a great as the sealing part will fit over any screws.. A good neat job done.
