These super smooth freerunning cars and tracks are used in everything from sliding seats to window washing apparatus and from exercise machines to acrobatics. Loads move virtually free of any friction. The recirculating Delrin ball bearings are held captive so the cars can be easily removed from the tracks. The utility cars are derived from the toughest and best quality marine equipment but are simplified ready to accept your own customisation. The flat top surface is provided with two tapped M8 holes at 38 mm centres ready to accept your bolts or eye nuts. The track comes in either low-profile or a tough beam-section with built-in strength for spanning gaps. 4 Use them for smooth-running stage machinery 4 Perfect for sliding trap covers 4 Friction-free scenery sliders 4 Indoors or outside 4 Maintenance-free — just flush with clean water! 4 Tracks can be supplied rolled to compound curves — please phone our Rigging Manager for details
