The Hilman 15 Ton Rollers have Swivel-Locking Diamond steel grid tops and loose Preload Pads.  KRS-15-SLD kits include everything needed to make those heavy moves: (4) professional quality Swivel-Locking Rollers and (2) full length steering handles in a steel storage case.  RS-15-SLD complete roller sets contain the same rollers, pads and handles but are provided without the kit box.  Hilman FT Rollers are ideal for heavy equipment moving, machinery installation, and maintenance.  Just lift the load, set the rollers, and move.  Swivel tops allow equipment positioning in even the tightest quarters.
