Attaching Aluminum Blast Gates To Metal Pipe How?

[richard poitras]

How are you guys attaching your ABG to your metal pipe? Are you pre-drilling the cast aluminum and screwing the pipe to it? Or just using clamps and sealing with tape and or duct seal? Or how?

I got my entire metal duct installed and only have the blast gates and hose to attach. I currently have the two wire type band clamps to attach the hose to the pipe and gates. But the gate to the metal pipe is where I am not sure of.

Thanks Richard

I used rivits after pre drill. Then sealed.

Like Mike, I drilled, riveted and then sealed the joint.

I just used RTV silicone since I ran out of clamps, 10 years later still holding strong!

Pre-drill and hand drive self-tapping screws in. Silicone by itself will work too but it's a headache to get the assembly apart if you ever want to rearrange things.

Pop rivets and aluminum duct tape.

Thanks guys it’s off to the shop for install…

Rivets work great on my system. I also used rivets on all my pipe joints. Simple and easy to use.

Pre drill and screws here. Figured it would be easier to disassemble than rivets when I moved into the new shop.

Predrill, screws and silicone. If you don't seal with silicone, tape or some kind of sealer you will hear a big sucking sound, add it all up for several gates, wyes and bends and you loose a lot of performance.

A Harbor Freight pneumatic rivet gun is awesome too LOL.

Well your probably done by now, but I'm with Rod on this one....self drilling screws;)

good luck,
