First Production Run Sold out!

The first run of SpaceLocks have been delivered and are being put to use! Stay tuned for a second run, we are tweaking our manufacturing process before making more.

Weblock Specs:

  • Breaking strength: 42kN

  • Working Load Limit: 8kN

  • Connection point diameter: 1in

  • Weight: 340grams

  • Designed for 1in webbing

  • Material: Aluminum 6061 T6

  • Not approved for highlining*

* with a breaking strength of 42kN, the SpaceLock currently does not meet the ISA standard for highline weblocks, therefore we are not advertising this product for highlining. 

While we cannot specifically advertise the SpaceLock for highlining, the use-age of the product is up to the user. The SpaceLock will never break when used under the Working Load Limit, and it is the responsibility of the user to know the forces being exerted on the product. 

  • $140 for the base weblock with custom engraving
  • $10 for shipping (US only**)

Clean Rigging

With the SpaceLock, clean rigging is the norm. With a large one inch wide connector point, the SpaceLock is compatible with any soft connector such as soft shackles, soft releases, and even the anchor sling threaded directly through the connector.


Each SpaceLock is made to-order, so you get to choose what yours looks like. With in house anodization, you can choose the exact color of each part of your SpaceLock. Furthermore, for an extra fee you can get yours custom engraved with anything you want.

Made in the USA

Each SpaceLock is manufactured completely by our founder Caleb Beavers, in a small machine shop in Boulder Colorado. You can watch the process in the making-of youtube series here.

Break Tested

Thanks to Ryan Jenks over at HowNotToHighline, we had a few of these prototypes slacksnapped. They were pulled against each other and one of them broke at 42kN, while the other had just started to deform.
