Product 1/3
These top-of-the-line chocks prevent sliding or creeping of vehicles and equipment under any weather conditions, with curved surfaces to fit tires and patented teeth to sustain the heaviest loads. Every chock is insured against breakdown, and features a newly improved underbody.
They are available in three models: Heavy (72,000 lb. cap); Medium (55,000 lb. cap); and Light (32,000 lb. cap).
Heavy Duty chocks exceed the new 1901 NFPA standard of performance criteria by 33%. One Heavy Duty chock holds a municipal pumper on a 15% grade, and two will support a pumper on a 30% grade.
