The W.E. Trimmer Boot Cover™ protects all of the trimmer engines plus the gas tanks that are on the rack at the same time. Made with the same high quality materials and workmanship as the W.E. Trimmer Covers™. Opening secures with hook and loop fasteners. Two sizes available - 34" long and 44" long. Measure your trimmer rack from the top of the top trimmer to the bottom of the bottom trimmer on the rack for correct size.
