TrafFix Devices: 43" Sentry Water Cable Barrier Wall TL2/TL3, White, w/ T-Pin, Fill Cap & Drain Plug.
The Sentry is intended as an alternative to cumbersome concrete barriers in a construction work zone. The Sentry has been tested and passed all TL-3 light and heavy vehicle impacts at 62.5 mph (100 kph). Molded into each Sentry are four (4) 3/8" (9.5 mm) diameter galvanized stranded steel cables. Multiple Sentry's can be connected together using interlocking knuckles and a 1-1/8" (30 mm) diameter galvanized steel T-Pin to form a barrier wall to protect impacting vehicles from entering on-coming traffic or a work zone. Each Sentry module has in-molded stacking lugs for easy transport and storage.
The Sentry is lighter than concrete median barriers and requires no anchors making it ideal for use on bridge decks.
