    Searched around everywhere for this seal then found it on the jcphardware website with a clear description and perfect image that matched what I needed. It’s great as you can order by the meter and it’s brilliant quality and easy to fit. I used this on my UPVC windows and frame and definitely noticed the effectiveness of it.

  • Great stuff

    Been looking everywhere for this seal, then found it here. Great price, easy to fit, looks exactly as advertised, well pleased with it. And best of all it stops the draughts :)

  • Good fit

    Great to find a good fit for our windows, after being told to buy new windows instead.

    It fits! Unlike many other gaskets (including other Qlon codes - tip - if you are trying to find the replacement seal, get a micrometer and measure all the different lengths/widths to find the correct code) it fits perfectly in my mid 1980's double glazed units. Tried other Qlons, but too narrow. Easy to fit. Would recommend.
