Harken Offshore Cam-matic Cleats Wedge Kit . Harken Cam-Matic cleats are legendary for smooth positive operation when holding and releasing control lines. Three rows of Delrin ball bearings allow the jaws to open or close smoothly under the highest loads. Light springs allow the cleats to open freely so the teeth do not have to be sharp and your line lasts longer. Use models with aluminum jaws for high loads or when the line will be drawn through the teeth for adjustment. Models 423 and 365 have carbon fiber jaws for lightweight durability. Cam 423 requires two 8 RHMS. Cam 150 and 365 require two 10 FHMS. Cam 280 requires two 14 FHMS. Each ShWt 0.5
