I'm not sure if anyone can use this, but I have a travel stairgate that is missing the 2 side pieces. I had intended to get some wood to replace the metal pieces, but never got around to it.
Because it's a travel stairgate, it fixes to the opening by screwing rubbery disks, so that it is stretched tightly. Therefore, it may not need the side bits.
It measures roughly 35" wide x 32" high.
Collect from New Tupton, although I'm in Hillsborough, Sheffield on Wednesdays, so could be collected from there.
