whats this bit called and can/should i get a replacement?

[skyflyer]

On this block (stock picture)

There is a "d-shackle" attachment fitting, but it is thin strip not round bar and held in with a pin and split ring not a screw.

I noticed that the one on my own block had become twisted out of shape and wondered if I can gat a replacement but all the d-shackles I see are round bar type.

Probably better to replace the whole block but I just wondered what the correct name is and if they are obtainable on their own?

Cheers

That's a budget Barton single swivel block, and if its distorted its obviously not up to the job, you can indeed get decent quality versions.

there are flat "D" shackles made & I have swopped them
You just need to find one
You may even find a wide gape round shackle whose pin fits through the holes

That's a strip shackle.

strap shackle: tends to be weaker and more prone to plastic deformation than solid bar.

Most chandleries have those, often hanging on a bit of string rather than on the main racks or pigeon holes.
They are cheap enough to keep a few spares.
If your one is distorted through load rather than accident it may be you are getting near the maximum load for the block. Consider upgrading.

AKA 'rigging link' when it's a clevis pin and ring, not a threaded pin.
