This padlock suits any size Hoselink Retractable Hose Reel.
It fits into one hole of the hose reel pin at the underside of the wall bracket, thereby securing the hose reel to the bracket.
The brass 30mm padlock comes with 2 keys. Given it's use outside, spraying occasionally with a lubricant may be of use to keep the key well working smoothly.
NB: Unlike the standard wall bracket, the reel cannot be locked on to the Hose Reel Post using the padlock or any other method.
