Brand: SPA Design Racing Products
These are the same cables as supplied with SPA Design fire suppression systems.
Each cable features a plastic-coated metal sheath (1/4" OD) with mounting hardware for each end, a red plastic T-handle marked "FIRE" in white letters, and a barrel stop clamp for the 1/16" inner cable. Available in 6 or 12 foot length. Each length is easy to cut shorter if needed. The T-handle end requires a 0.365" (3/8") hole for mounting. Sold individually.
This type of pull cable is also commonly used as a remote actuator cable for a kill switch. Just sand off or paint over the "FIRE" on the handle for other applications.
