¶The measurement to take
Slide a ruler behind the radiator and measure the horizontal distance between its back and the wall. That is the only dimension that matters. Put it in your order note: I cut the blade 3 mm thinner, so it drops in without forcing and stays put.
¶Air keeps moving
Laying a board flat on a radiator kills the convection and bakes the wood. Here the gusset holds the board 60 mm clear: warm air rises between the radiator and the shelf, and your board rests on nothing hot.
¶Why ASA
Same material as the standard model, the one used for car exterior parts. It holds past 100 degrees where PLA softens and creeps.
¶Sold in pairs
A shelf needs two brackets. The menu covers one to four shelves. The board is not included.
