Size is listed as 24" W by 24" H. To pick the best fit, measure your equipment’s horizontal and vertical circumferences and halve them to estimate width and height. Velcro closures secure the cover in place, and extra nylon ties help keep it steady. For added security, grommets can be locked with a chain to deter theft.
