ISC Spring Locking Medium 3/4" Rigging Block
The ISC RP055 Medium 3/4 rigging block is manufactured using Hot Forged Technology, combined with high quality materials and components. These blocks are rope friendly, durable and extremely robust. These features combined give maximum security and strength, when the block is rigged as part of an impact system.
Apart from the aesthetically pleasing curves, the ISC impact pulley is designed to work (together with textiles) to absorb the huge forces which are created by the harsh dynamics of heavy arborist work. The side plates are produced using the best quality hot forged Aluminium and the special manufacturing process allows these pulleys to offer a highly impressive strength to weight ratio.

Heavy hitter
I use this block for medium to heavy rigging. It has a very efficient pulley with smooth edges and is appropriately rated. The 200 series has made the necessary improvements with a newer low profile locking push button with rotating axle vs the push/turn axle and the 200 series are lighter. However, the ISC RP 055 is a tested and proven arborist block that gives you a lot of bang for the buck and it lasts.
Trust the right gear!
Use the right tool for the job. This ISC block is reliable and trustworthy for big rigging jobs. It is not too heavy, easy to open and also inspect. I run 5/8 rope with it. Worth every penny.
