Stress Relief for Wires in Planned New Conduit

My masts do not have conduit for the wiring and I am adding this as part of my refit and I'm confident I've got the how to install the conduit part nailed down. It's comlicated but doable to attach the conduit with rivets, but in a mast with an intact masthead how do I add stress relief to the wires so they are not just dangling from their masthead connection?

Same question at the spreaders as well.

Thanks,
-p

Mine is a multi conductor and is actually armored..I think that transfers/carries the weight of the wires.

Good question(s).
Firstly, Valium won’t work; because you’re actually seeking strain relief, not stress relief.
There are a number of commercial products that might suit:

“Skintop” Strain-Relief Connectors ➥ Lapp Online Catalog

“Kellems” Strain Relief Cord Grips
Strain Relief Grips - Strain Relief - Electrical - Grainger Industrial Supply

first off HA!

Second off those look great if I'd be able to put my hands inside the mast, but how can I pull wires through that strain chinese finger cuff inside the mast?

Maybe you can put them around the wire before you pull it?

You’ll probably have to remove the Masthead Fitting (truck), to access the inside of the mast. Having dine so, you could probably just use a couple of tie-0wraps to cupport trhe cable.

However:

Use the Wire Mesh Pulling Grip to fish the wires up the mast.
Then, use a pumping action to “walk” the grip over the cable by bringing your hands together and then relaxing them until the end of the cable protrudes far enough through the throat of the grip* to reach from the point of exit & fastening, to the mast-top device.

The “Chinese Finger Cuff” strain-relief grip is also known as a Pulling Sock, Basket, or Kellems grip.

Don't think I'll be cutting off my masthead since we just painted and it's not bolted on. but I think it would be possible to assemble the wires and pull a fitting and the Kellem's grip through the conduit.

Gord you are always a fountain of knowledge !
