Quick plumbing question...

[Delphinus]

Is the holder itself going to be subject to spray from the tank or sump? If not then I'd just use some metal strapping. I don't know the name of the stuff but it's like the most standard thing you can get at any hardware store, it looks like tape but is metal, has holes along the centerline at 1cm (or thereabouts) intervals so you can screw it onto a wood surface and so on.

If it is subject to salt spray then I'd just use a large zap strap (you can get them in pretty mondo large sizes). For a 1' drop you may need to daisy-chain them but they'll work fine.

How would you recommend attaching the zip ties to the plywood?

Thanks. I may look into the strapping and heat shrink today at HD. What exactly is the heat shrink? I mean it sounds very obvious but Im not sure. Is it like the stuff used for wiring?

Mark's stuff is the stuff I was trying to describe. That should work well.

If you do end up using cable ties though, you can get these little stick-on cable tie mounts for them (again available more or less anywhere that sell these sorts of things .. HD/Rona/etc. or electronic supply stores)

And lots of the holders are made to take a screw. Depending on type might need a countersunk head screw for clearance of strap.

I think Home Depot actually carries some strap iron that comes pre coated with some kind of plastic. You just need to cut to lenght and then seall up the cut ends with a bit of silicone. You can also vover up any retaining/fastening screws with a dab of silicone

It's a plastic tubing that shrinks when heated.

Might have a hard time finding long lengths from Home Depot but if go to a electrical supplier can get in meter lengths or rolls to 50' or more.

Here's the type of strap I use if hanging a distance. Also good for securing ballasts and other parts and pieces.

Never done it but water spray a concern could thread it through some heat shrink and use nylon fasteners.
