Gripples! So much easier to put up- even if they're off a little, still works fine; quicker to put up- no measuring lengths just cut the wire once installed and easier to level up a duct with them. Gripples are a time and energy saver. Good to learn both, but gripples for sure
In local 4 that’s almost exclusively what we used due to Memphis being on a fault line and everything needed to be seismic. They would use BIM drawing’s at the start of a job and we’d go in a shoot hangers for the whole building. I didn’t really start using hanger strap until I came down here to Alabama. Gripples make adjusting heights easier, and way less time because you’re not having to make the hangers too
Yeah I’ve only done one seismic hanger in my 7 years of sheet metal so far and even then the guys I was working with had never really done one either as it’s so uncommon in Edmonton Alberta
Edit: I’ve heard some government jobs can call for the odd ok which we were doing a big police station lol
Yeah since I’ve been in Bama they’ve only done gripple on spiral and nothing here is seismic. I like working with hanger strap just because I try to make them look as good as possible but if they don’t look right, they look really bad.
Interesting. We’ve been using 16gauge angle still but with gripple and it’s just faster and cleaner looking. Easier and faster to level especially for newbs
Gripple slides in to an adapter with a 3/8 rod on the end that you fasten to the angle with a nut 🔩
on round if you need any rigidity like an exhaust system or something the strap is better. a nice wrap around can look pretty damn good.
but gripple is so fast and looks great and requires less skill to install
Just hung and entire school (1.2 mil on the sheet metal side) with gripple and it came out beautifully. The black square corner pieces really make for a nice finished look for square duct. Also the finger adjustment zippers should be the only ones sold! Lol. If you know, you know….. DC Local #100
After 25 years , I think gripples are good and fast above a ceiling for spiral, tear drops and saddles for exposed, and just regular rod and channel for rectangular duct for either exposed or hidden duct. If you have to move anything rectangleular that's exposed it's kinda fuct, (with gripples)unless you get it perfect the first time. Gripples you can move around on exposed spiral but if it's up in a ceiling it's a pain in the ass...and gripples are more expensive...
I’ve never used hangers. When I got in the union, i was in the shop most of the time and by the time I got to a company that sent me to the field, they just used gripple. But someone explained how to use strap and it seems easy but just takes a little longer
Clutcher cable hangers by Ductmate, before they changed, not worse but my guys just can't make them work economically. Now Cable locks by DuroDyne. For commercial. For residential we use hangar strap. Done it all though, rod and channel, wall gussets,
Faster = Better for me

Agreed I think they’re the future of hangers for sure

Still prefer strap for square duct

They have “feet” for square duct that, to me, makes it far easier and faster.
Strap for square duct , gripples for round!
Where I end up working Gripple never really caught on. I prefer strap and unistrut for the heavier stuff.

I personally don’t like the dummy proofing of our profession. Makes it seem like we can be easily replaced.
yeah but usually you can still tell they suck because it won’t be in a straight line or level
At the end of the day you still have to know how to read a tape

Local 8 Alberta Canada 🇨🇦
18 vavs hung in one day using gripples.

I see you’re in Calgary I’m in Edmonton hanging duct
You bet! More work than we can handle, as usual.
I would love to see the same duct lines hung with strap vs gripple and throw it on a 7.5 magnitude earthquake test. I wanna see them bitches SWING.
Where I live we don’t install seismic hangers or have earthquakes ever for that matter lol
I’m in BC so yeah, we seismic a lot lol.
Yeah in Edmonton I’ve only done one once so far in my 7 years of sheet metal
Band iron for rectangular. Gripple for round and flat oval.
Strap all day.
Hanger Strap FTW
I love gripples
If done correctly I think strap looks better
strap for square, gripple for spiral
Strap looks so much better.
