Allen 30mm Back To Back Block

A2038

Using the same high quality material and precision engineering as the 20mm dynamic range, our 30mm dynamic bearing blocks offer best in class strength and reliability.

They may look similar to some of our competitors but take a closer look at the finer details of their design, the quality of the materials and construction to fully appreciate the difference.  From the patented high strength 316 stainless steel line friendly ultra strap, to the soft contours of the sheave and cheeks moulded from advanced engineering polymers, patented dynamic bearing technology featuring twin rows of 316 stainless steel ball bearings all held together with a meticulously designed 316 stainless steel jacket, our blocks are the strongest and best available on the market.
