I'm interested in getting some t-bolt clamps for my pipings but not sure which size I need. I know I need four 3" clamps but the rest I'm not sure about. I believe I need the 2.5" t-bolt clamps which can range from 2.66-2.97". Please let me know so I can place my order asap. Thanks.

 

i am using all t bolt.

you'll need 3", 2.75" and 2.5". they are sold according to the nominal pipe size they fit.

just look at the install manual and count how many of each you need.

i ended up with a few extra 3" and 2.5" ones i think
