Easy to install, all at a good price. I decided the house needed more loft insulation. With lots of items in loft I needed something to put the loft boards over the new insulation, these were the best found with brackets that slot over the loft beams making them easier to position. I screwed them to the beams and then placed the loft boards on top and also screwed them down through the stilts, once done they were solid. I would recommend that you buy these for keeping the loft usable when increasing the heat loss through your roof. To add to this, they were good price. The more you buy the better the price for each strut. Glad I found them.
