Equilocker – Longline Linelock for 25 mm Webbing

The Equilocker by Sigma Slacklines – the high-quality longline linelock for 25 mm slacklines.

Thanks to its generous dimensions it also takes thick webbing or doubled slacklines. Direct connection to 12 mm stainless steel shackles or 2 t steel shackles, no loops or slings needed.

The front pin (12 mm, freely rotating) allows comfortable pre-tensioning by hand. The large central redirect made of anodised 7075 aluminium ensures maximum use of the breaking strength. Framed by 4 mm thick, deburred and glass-bead-blasted stainless steel plates.

Why a longline linelock?

The longer the line, the higher the tension and the sharper the bend the webbing has to survive at the fixing point. A tight redirect radius costs breaking strength exactly there. The large central redirect with a diameter of 34 mm keeps the radius wide and the reserves high. When rigging, the front pin lets you pre-tension by hand before the pulley takes over. That saves travel and nerves.

Equilocker or Equilocker Plus?

The Equilocker Plus has an additional quick pin for direct soft release attachment and comes with a 10 m soft release. If you rig very long lines and want to release the tension in a controlled way, that is the right choice. For everything below, the Equilocker is enough.

Goes well with: stainless steel shackle 12 mm, Sigma ReBL and the pulley. To get started with long lines: Longlines: getting started.
