A cooling bed plate transfer grid insert which is height adjustable independently of its mounting to the grid. The insert has an outer frame which is clampable to the grid and an inner frame supporting a roller'and which is clampable to the outer frame and height adjustable'relative to the outer frame so that the mounting of the outer frame to the grid need not be disturbed when adjusting the height of the roller or when replacing the inner frame and roller assembly.for repair of the insert. The inner frame is thus easily and inexpensively replaceable without the necessity of replacing the outer frame. The replaceable inner frame includes stationary bearings for the rotating roller shaft to provide improvement in wear life of perhaps about 200 per cent. Springs are provided to.allow the roller to flexibly move downwardly under load of plates being moved thereover so that each of the rollers underlying a plate bears its share of the load, but the rollers are biased to the desired unloaded height. A ramp is provided on the inner frame for deflecting the plates being transferred onto the roller and thereby eliminating or reducing "catch points" which may cause thin plates to bend. The end portions of the inserts have mating tongues and grooves allowing successive end-to-end placement of the inserts.
