Which type of braid structure is easily spliceable and commonly used for slings?

The correct answer is that a loose braid structure is easily spliceable and commonly used for slings. Loose braids consist of fibers that are woven in a way that creates spaces between them, which allows for greater flexibility and movement. This design facilitates easier manipulation when splicing, as the strands can be separated and woven back together with less friction and difficulty compared to other braid types.

Additionally, the loose braid's characteristics make it particularly advantageous for joining ends or creating loops that can withstand the dynamic forces encountered in applications like slings. The inherent flexibility allows it to accommodate bending and loading without compromising the integrity of the braid, making it suitable for various rigging and lifting tasks where splicing is often necessary.
