Abstract
A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.
