The Neomounts by Newstar ABL-875 is a brake lock for the castor wheels of the FL50S-825 and FL55-875 trolleys. To prevent unwanted relocation of the trolley, the brake of the double castor wheels can be blocked using the ABL-875. The bright blue colour is a clear reminder for the user that the wheels are locked. The ABL-875 comes as a set of 2 brake locks.
