Boxtown Team Ladder Carrier is designed for A- frame fiber glass ladders. Size ranges 4ft- 12ft. Designed for 4-8 but will work on 10 and 12 ft (force fitted on).
Ladders, themselves, DO NOT have a handle. This causes the worker to carry it by placing the fingers in the crevice points of the ladder, which creates pain after less than 30 seconds of carrying.
