What to Compare Before Buying
- Line diameter: The maximum line diameter is 5/16 in. (8 mm). Make sure your control line matches this limit.
- Load requirement: The stated maximum working load is 500 lb (227 kg). Compare that figure with the load expected in your rigging.
- Space available: The block is 2 in. (51 mm) long. Check the mounting area and nearby hardware for fit.
- Block style: This is a single wire bullet block. Confirm that this block style matches the control line application you are setting up.
Before You Decide
Confirm the single wire bullet block style, the 5/16 in. maximum line diameter, and the 500 lb maximum working load before choosing an offer. The 2 in. length and 1 oz. weight are also useful checks if space and overall setup weight matter to your rigging.
