What is the safe working load for different RT 6 products?

30 June 2021


The RT6 range is designed to span from coastal to deep ocean and light work to heavy work. With releases the Working Load Limit (WLL) is always a key piece of information, alongside proof load, breaking load and the maximum safe release load. But what are these for our RT6 range?

The below table summarises the limits across our entire RT6 range.

RT 6-1000 RT 6-3000 RT 6-6000 RT 6-HD Heavy duty acoustic release frame (RT 6-3000 & RT 6-6000) Type 7869 Heavy duty acoustic release frame (RT 6-3000 & RT 6-6000) Type 7988
