3. The 18 mm blocks ship with lashing line. Use
two laps of supplied line to create four strands to
match the maximum working load of the block.
Securing Block to End of Larger Line
Do not use HCP1438 line supplied with 18 mm Fly block. Use a larger, stronger line that exceeds the
block's breaking load to account for loss of strength due to weakness of knots, UV damage or chafing.
Run line through head, through mouth, and out head.
Secure with a bowline with end whipped to loop so it stays secure. Consult knot tying book or see
www.harken.com/knots.
Securing Block to End of Larger Line
Securing Block to Large Diameter Object
When running line around large-diameter object such as a boom, cross line each time you pass around
the object.
Blocks 2161, 2171, 2173:
Use sailmaker’s twine or similar to secure lashing strands to head. Use
sailmaker's twine or similar to hold lashing strands crossed as shown below.
Important! If lashing line is pushing outwards on head, it can break the block. Check to make sure
each lap crosses separately as shown in the photo at left below.

Replace
damaged line immediately. Replace line with no visible damage every
two-years.
Use Harken replacement line, but if using own line, see “Using
Alternate Line, Knots and Splices” and chart on back page for important
information to help you select the correct line.
