D-Rings Vs O-Rings

[EricDobson]

I'm wondering what the considerations are to using O-rings vs D-rings? When is it better to use each type? Is it primarily a functional or visual decision?

Thanks!

For me, functional comes first because most of what I make is for large working dogs.

It depends on what the ring is being used for, if it's not really functional, then it doesn't matter. Go for the looks.

If it performs a function, I look at the width of the strap in sizing the ring. A lot of my d-rings are on a stationary part of the project (a dog harness). Straps (leads, connecting straps, etc) will attach to the round part of the d-ring. If my function is to connect any number of straps, I use a properly sized o-ring.

Sometimes I may sew in a section of "wear leather" to lessen the amount of wear to the edges. If the strap is too wide for the o-ring (or d-ring for that matter), the edges will wear through in no time. For example, if I use a 1/2" strap, I will go for a 1" (minimum) o-ring or d-ring.

Hope this is clear enough to help.
