Chock holder patented, easy to use and equipped with a double integrated security system. The new Double will simplify the operator’s work, as it will not be necessary to press on the handle to open or close the chock holder. It will be simply necessary to slide the handle on the back of the chock and it’s done! The plastic handle marked by a rebated locking system, ensures a stable and secure hold of the wheel chock. Double 46 is provided with some inner clips working as a second security system, making the use of other accessory security systems (cotter pin, springs) unnecessary.
