*Bargain Price* A good brass-bodied combination padlock suitable for shed and bicycle security where you can change the combination yourself and avoid the hassle of keys!. 10 year guarantee from Squire. 0.5kg Note: Not suitable for use with 16mm chains! Not recommended for motorbike security or other demanding applications.  Would be around CEN2-3, and very handy when keys are awkward (e.g. if several people need access whilst still retaining decent security).
