Ideal for both indoor and outdoor applications, this padlock is backed by a limited lifetime guarantee, making it a reliable choice for securing sheds, trailers, storage units, and more.

## Description

Rugged stainless steel padlock with 10,000 possible combinations offers maximum weather resistance and protection against bolt cutter attacks for indoor and outdoor use.

Review: Does the job well - A very good and strong padlock
Review: Easy to set the new combination, very secure design. - These are the best value padlocks I have found. They're so solid, I bought them for the garden sheds to replace the key ones since multiple people in the house use them. Being able to set the combination is a handy feature, I could set them to something all the users can remember. I think you would need a grinder or something to hack off that lock because the design is too secure for an opportunist. It's only been in use for a few months now and there is no sign of rust or weathering, I'll update the review if that changes, but so far it's weatherproof.

### ⭐⭐⭐⭐ Packaging !
*by D***G on 11 September 2021*

Never seen package like this before - 15 minutes entry time ! You need to unlock it, before you can take it off the packaging ? (Stops thieving from shop displays maybe) After discarding the loose rubber facing, and filing off some sharp edges, we have a very good lock. Love the way the turning dials are easily accessed from front and back, and the large gate for cables. Robust enough to withstand a "two spanner" attack, but unsure if the reset key may provide a way in. The outside SS cover was very smooth, but inside corners are sharp and hinder the clasp opening. Feels like good solid protection for items inside my garage.
