Harken Airblock 16mm Double

The Harken air block offers a very high load in an extremely lightweight block. Excellent for control lines. The block itself is only 1-1/8" long; overall length is 1-11/16. The 5/8" sheave will accept line as large as 7/32". 450 lb. SWL; 1200 lb. breaking strength. Harken #406. Hobie Cat® uses #H406 for this block.

The 16 mm is Harken’s® smallest block. It is perfect for small synthetic control lines found on high-tech dinghies. The patented bearing system uses stainless steel balls in a captive grooved race.
