Ideal for securing bicycles and garden equipment, the Pragmasis Shed Shackle improves security for wooden or metal sheds. It reinforces a large area of the wall of the shed so that a thief would have to saw or smash a huge section, making a lot of noise and taking a lot of time. Weight 2.5kg
Easy DIY fit. Easy-to-follow and thoroughly illustrated instructions are included.
The first photo above shows a typical installation in a wooden shed. The modular design of the Shed Shackle allows it to be fitted in a variety of ways, providing maximum flexibility for different shed designs and maximum convenience combined with good security.
A later photo above shows the wooden shed fitting kit that is included, with a drill bit as well (a different kit is provided with the Metal Shed Shackle).
Further photos show how the shear nut looks after shearing, and a coach bolt with a shear nut before and after the hexagonal head has been sheared off. You can see that a sheared shear nut leaves only a smooth conical surface - simple but effective!
Longer bolts are available at extra cost for wooden sheds with unusually thick timbers.
