The heavy duty forged d ring D ring is a fixed mounting plate, which will make it the best upgrade.
The most important thing is to use a lot of iron rings on deck.Unlike the D ring, it has forged a bar in the middle, and when we use it, it can pull the belt up twice, so it is much safer than the D ring.
This mounting bracket D ring is made up of a hot forging body rather than a welded ring.
This gives a large number of loading factors, the cantilever material is high carbon steel or alloy steel or stainless steel.
After forging, heat treatment can be done to make it harder.Then sandblast and grind the cutting line.This process makes the cost slightly higher than the non-griend D ring.Then weld it to the mounting bracket.
Its surface treatment is hot dip galvanizing or paint.
