Anchor Size 



- Small anchors (<3,000 lb) often exhibit higher efficiencies (by as 

 much as a factor of 1-1/2 to 2) than anchors 10,000 to 30,000 lb. 



- Manufacturers' claims of constant efficiency with size .based on 

 geometrically similar designs (dimensions ~ anchor wt ) . Data 

 do not support this as a general rule. Refer to section on 

 Anchor Capacity.

 1980c)
