Q: Where can I buy Master Lock products?


You can find Master Lock products in most DIY stores, and in a selection of mass market stores, hardware stores, sporting good stores, web stores and professional resellers. See our Where to Buy section to find your nearest point of sales.

Q: How to choose the correct strap for my application?


When selecting products to secure a load, consideration should be given to the required lashing capacity and whether the load is being transported.  The size, shape & weight of the load and transportation environment if applicable should also be taken into consideration.
For stability reasons freestanding units of load have to be secured with a minimum of 2 lashings and 2 pairs of web lashings for diagonal lashings.
The selected lashing system should be both strong enough and of the correct length for the mode of use. Basic lashing rules:
- Plan the fitting and removal before starting a journey;
- Keep in mind that during journeys parts of the load may have to be unloaded;
- Calculate the number of web lashings according to EN 12195-1/1995;
- Only those web lashings designed for frictional lashing
- Check the tension force periodically, especially shortly after starting the journey.
