ISC's recently updated RP055 is a 3/4” capacity spring block. Its compact design makes it perfect for the working arborist. As with many of ISC's products, the RP055 features a unique upper sheave.
The user can easily manipulate this sheave, which eliminates the chance of dropping it. The side plates are made of thick aluminum and have a blue powder coating. This choice in materials means the RP055 has a superior working life, and is resistant to many types of wear.
