RBS Rocket Tensioner Stainless Steel Key

Stainless steel key designed to be used with the RBS Rocket Tensioner batten ends.

The RBS Rocket Tensioner System doesn't only serve the purpose of keeping the batten in the sail pocket but also gives you a clean and easy way to tension your battens from the aft end to the desired shape and position.

The RBS Rocket Tensioner was developed with the coordination and cooperation of several top sail designers. Lightweight and low profile it was designed for a clean and easy way to tension both flex and compression battens from the aft end.

How It Works

• The rocket tensioner was designed to be used with a spectra loop.
• Tensioning the batten will apply pressure to the line or webbing keeping the batten in place.
• To work properly the batten should be trimmed up to 2” or 50mm from the actual length. If you need to trim the batten, always trim from the aft end.
• For easier installation back off the tensioner screw around 1/2” or 13mm to be able to place the loop or webbing on or off.
• The tensioners are supplied with a 1.750” or 44mm length stainless steel screw that allows approximately 1.250” or 32mm of adjustment.
• Tested for up to 500 lbs of load. (ex: a CB19350 diagonal head batten will produce roughly 700 lbs of load and should not use a tensioner)
• Never lose another batten out of the pocket while sailing again!
