Tired of water-damaged freight? Use our high-volume smoke candles to thoroughly leak-test your dry vans and shipping containers.
Superior Signal® Smoke is an essential tool for trailer repair. This highly visible smoke is perfect for checking the integrity of semi trailers and containers. One or two 3C Smoke Candles readily fill a 40 ft container or 53 ft trailer top-to-bottom and front-to-back, letting you instantly identify punctures and rust holes, popped seams, and leaks around doors seals and hinges. No pressurization necessary. Just light the candle(s), close the doors and in minutes, dense, white smoke escapes from even the smallest leaks in roofs, floors, sides and doors.
Superior Signal® Smoke is non-toxic, non-corrosive and leaves no residue. It is safe for workers and safe for use around freight.
Don't trust the "daylight" test! Use Superior Signal® Smoke candles whenever a thorough check of dry van and container integrity is required.
