Zip-Tie Top-Post Battery Terminal Boot
A cover for car, marine and mower top-post battery terminals that replaces the missing or cracked rubber boot. The open-bottom hood's inside measures 36 x 52 x 32 mm, so it fits over the post and clamp. A 13 mm U-channel takes battery cables up to about 12 mm OD, and a zip tie through the slot underneath holds the boot to the cable. It keeps tools from shorting the post and slows corrosion. Print it in red for positive and black for negative.
