Common Concerns Answered
Is the stanchion clamp difficult to adjust?
While the stainless steel clamping ring provides a secure fit, initial adjustment may require a firm grip. However, once set, it offers reliable stability.
How durable is the composite body?
The UV-protected composite body is engineered for marine environments and offers excellent durability against sun and saltwater. While robust, extreme direct impacts could potentially cause damage, as with most composite fittings.
Is a ratchet block truly necessary for my sailing needs?
A ratchet block offers significant advantages for managing furling lines by providing a friction brake that prevents accidental unrolling and reduces load on the crew. This is particularly beneficial for single-handing or when sailing in strong winds, ensuring safer and more controlled sail management.
Frequently Asked Questions
How does the Barton Stanchion Ratchet Block control furling lines?
The block incorporates a ratchet mechanism with an integrated friction brake. This mechanism engages when the line is under load, preventing it from slipping back and allowing for controlled easing or furling of the jib.
What is the maximum line diameter this block can accommodate?
This Barton Stanchion Ratchet Block is designed to accommodate lines up to a maximum diameter of 10mm (3/8").
How is the Barton Stanchion Ratchet Block fitted to a stanchion?
The block features a unique adjustable angle clamp specifically designed to fit standard 25mm (1") guard rail stanchions. The clamp utilizes a stainless steel ring to secure the block to the stanchion.
What materials are used in the construction of this block?
The block is constructed from a UV-protected composite body, marine-grade 316 stainless steel for internal components, and features a 12-faced anodized aluminum sheave, all contributing to its durability and performance in harsh marine conditions.
Can the swivel head be locked in place?
Yes, the swivel head can be securely locked in place using the integrated stainless steel lever, allowing for precise orientation and control of the block's lead.
