Ronstan Stand-up Base For Series 40 Orbit Blocks
You use this item with the Series 40 Orbit ball bearing and ratchet blocks, to create stand up blocks.
Low profile stand-up kit allows 0° or 90° alignment
The RF2454 stand-up kit features a clatter-free rubber boot and forged lacing eye with 5mm fixing holes with 38mm centre to centre.
You can attach the Dyneema® link so that the block is aligned with the stand-up base or across it. It’s a neat, low-profile solution which allows full articulation.
