Use: for construction of sliding elements.
Material aluminium runner, 3 polyamide rollers, 3 steel bearings, 2 M8x20 socket head screws, 2 M4x16 grub screws, 1 M8 square nut in galvanised steel.
Characteristics: the position of the central roller can be adjusted in order to offset any clearance between the seat and the side rollers (the 2 side rollers bear the load, while the central roller is exclusively used to recover clearance).
Warnings: manufacture for vertical fitting only; this part should be preferably used in the place of the roller with bearing Part 2053 for construction of sliding doors that require a higher load capacity (large doors). The runners must always be used in pairs.
