In the interest of making the carrick bend easier to untie, especially when tied in extremely large rope, the ends may be seized to prevent the knot from collapsing when load is applied.
This practice also keeps the knot's profile flatter and can ease its passage over capstans or winches.

The ends are traditionally seized to their standing part using a round seizing.
For expediency, a series of double constrictor knots, drawn very tight, may also be used.
 When seizing the carrick bend, both ends must be secured to their standing parts or the bend will slip.
