Panduit Lashing Ties are extra-heavy cross section ties that come in weather resistant or indoor use varieties. Both types are used for heavy duty applications with weather resistant ties having a greater resistance to ultraviolet light. These ties are the strongest Pan-Ty cable ties available. Weather resistant ties come in 19.8" and 21.8" lengths without a buckle, and an optional mounting clip. Indoor use ties come in 9", 20.1", 22.2", 28.3", and 40.1" lengths and include a buckle.
