Power cable reel with impact-resistant socket | JON21Z21510 | 10m (2*1.5mm²) | 5.945kg | ABS engineering-plastic housing; impact-resistant socket with YZ/PVC power cable, a three-pin plug, two two-pin sockets and one three-pin socket. The standard RVV cable is a flexible copper-conductor cable with PVC insulation and PVC sheath, offering good conductivity and stability. PVC sheath (RVV): good insulation, abrasion resistance, moderate cost and flexibility; suited to general workshops, service shops and conventional indoor power applications. Rubber-sheathed cable: softer, with good bending and abrasion resistance and greater environmental adaptability; suited to mobile work, frequent dragging or higher flexibility requirements. Drag-chain cable: good bending, repeated-motion and fatigue resistance; suited to automation, machinery stations, repeated movement and intensive use. |

Dual steel bearings maintain shaft and bore alignment and even seal compression, supporting sealing performance and durability.
The spring remains contained during installation and removal, supporting safer servicing.
An independent, enclosed spring housing helps prevent water ingress. A single-sided catch allows assembly and removal without screws.
A routing groove and 45° connection maintain the hose and cable bend radius, reducing excessive bending and helping preserve flow.
An adjusted outlet angle and shaped guide reduce bending and pulling resistance for smoother line movement.
A stainless-steel double torsion spring operates within its elastic range to support a longer service life.
Select the installation method for your bracket and configuration. Check the site conditions against the supplied drawings.
Reference mounting height: 2.5m above the floor.
Reference mounting height: 2.5m above the floor.
Bracket dimensions shown: 144mm, 72mm and 38mm; mounting holes: Φ8.5mm.
Bracket: 177 × 61mm; hole spacing: 156 × 49.5mm; holes: Φ7mm.
Follow the exploded drawing for upper and lower brackets, flanged Φ20mm aluminium tube and ST4.0×25 self-tapping screws. The wall-mount drawing uses M6 expansion bolts; fit washers when pre-tightening nuts.
Use a filter/regulator/lubricator only for pneumatic tools. Dust blowing and spraying need a filter/regulator without a lubricator. Check fixings and the installation against the official instructions; contact the manufacturer with questions.
