Add screw lock

The Screw-Lock is made from lightweight yet durable aluminium and has a 490 kg breaking strength, giving you extra security without adding unnecessary weight to your lead.

Weighing just 15 g and measuring 7 cm, it's small, lightweight and comfortable to use. The screw-lock mechanism prevents the gate from opening accidentally, while still letting you decide whether you want to keep it locked or unlocked.

Unlike our Twist-Lock Carabiner, the screw lock isn't automatic – you simply lock it when you want the extra security. It also features a swivel, allowing the lead to rotate freely and helping prevent tangles.

Here's how it works:

1. Choose your leash
2. Add the screw-lock to your cart
3. If you’re ordering multiple leashes and only want the screw-lock on one of them, leave a comment in your order or email us at hello@tassmark.com
4. Complete your purchase
5. We replace the standard BGB hook with the twist-lock when we make your leash

You can also order the screw-lock separately – perfect if you want to use it on a waist belt or other equipment. Fits up to 20mm width.

We know that leashes are a very personal thing. Need 130 cm, a line with a detachable handle, or maybe you’ve got a wild idea for hunting? We’re happy to help you create exactly the leash you want – in the right colour, width and with the clip that suits you best. We keep several types of hooks in stock and can also order others if you have something specific in mind. Email us at hello@tassmark.com and we’ll figure it out together.

Toys, however, can’t be fully customised – but if you have questions or ideas, get in touch and we’ll see what we can do.
