Alternating texture patterns in the boom area increases friction for less slippage. This eliminates the need to overtighten the boom, decreasing stresses on the mast.

No more than 10-15kg of pressure needs to be applied on the boom head lever for it to close. 

DO NOT OVERTIGHTEN!
Overtightening the boom head causes damage to your mast.
