Common Concerns Answered
I need a greater adjustment range. Does this turnbuckle offer extended open length?
This C. Sherman Johnson turnbuckle provides an open length of 11" pin-to-pin, which is ample for many rigging adjustments; however, some users may prefer even longer adjustment capabilities depending on their specific application. For applications requiring a longer range, explore alternative models with extended open lengths.
Is this turnbuckle heavier than other options?
The use of forged silicon bronze in the body contributes to its substantial build and inherent durability, which may result in a noticeable weight compared to less robust materials. This weight is indicative of its superior construction and long-term resilience in marine environments.
How does the breaking strength compare to all-stainless steel turnbuckles?
While this turnbuckle offers a breaking strength of 2,500 lbs, some all-stainless steel competitors may exhibit higher breaking strengths. The silicon bronze body provides excellent corrosion resistance and non-galling properties, a critical factor for longevity and ease of adjustment in saltwater, balancing strength with material benefits.
