Series 20 Orbit Block™ Range © Ronstan
Most competitive dinghy sailors would likely have used or seen Ronstan's popular 20mm single sheave ball bearing and HHL Orbit lashing blocks.
Ronstan has now added additional multi-sheave configurations as well as a lightweight cheek block to the range. Double and triple lashing blocks, including a double HHL version for higher load applications, offer sailors stronger and lighter options for multi-purchase control systems on modern high performance and foiling sailboats.
The 20mm sheave diameter will accommodate up to 6mm lines, and a 4mm lashing line must pass through the central hub to ensure they meet their published loads.
The RF25209 double lashing block is a lightweight 14g block with a maximum working load (MWL) of 300kg and a breaking load (BL) of 800kg. The RF25309 triple lashing block features the same maximum working load and breaking load and weighs just 21g. Both the double and triple blocks utilise Ronstan's proven 2-stage bearing system for high efficiency under both dynamic and static loads.
For higher load applications, the RF25209HL double block features stainless steel HHL sheaves with stainless steel ball races and bearings, providing a higher 450kg MWL (900kg BL) yet weighing just 26g.
