So, I recently did the essential upgrate to the spreader sockets to the Stainless ones from CD. The kit came with two compression tubes. I replaced the smaller diameter tube but found that the original design was without the 1 3/4" tube. I have been researching and asking everyone from Catalina Engineers to my neighbor's dog. The unofficial consensus is that it is nice to have in there but not necessary on the C25 with the older "beefy" mast extrusions. Has anyone here done this upgrade and NOT put in the larger compression tube? If so, any negative experiences? It is a royal pain to get in there and secured. In fact there is no mention in any directions how to secure it between the spreader sockets. At least the smaller one has a bolt through it... I am looking for opinions and discussion here. I think I know what I am going to do but just thought I would ask yall your thoughts. So let me have em!

I just installed the stainless spreader sockets (no instructions) and I'm a fairly accomplished mechanic. I can't for the life of me see how the large tube can be installed. I also don't get what the need for it is. I get the fact that there can be a good bit of inward pressure on the sockets but the pressure is spread over the entire socket plate. The cast aluminum socket had to be weaker and it didn't require a compression tube, did it?

The tall rig uses a different extrusion, is it a universal kit?

I cut a V notch in a pvc pipe and taped the compression tube to it with masking tape. Be sure to go behind the wire bundle or you'll never get past the steaming light. There should be a screw in the spreader cup that keeps it kind of in place until the spresder bracket is tightened.

<hr height="1" noshade id="quote"></font id="quote"></blockquote id="quote"><font size="2"><font face="Times New Roman">Yeah, what he said. I used a total of 4 compression tubes at the spreaders -- one on each of the three bolts and the large diameter thinwall one right at the spreader bar base, retained by #10 fasteners. (Actually cut from the same tube it appears.)

For those of you who haven't experienced the adventure of getting your old 3/8" bolt out, if it's stuck don't be surprised and don't get in a hurry.

Re: "<i>...the fact that there can be a good bit of inward pressure on the sockets ...</i>"

As I recall, most failed masts fold at the spreaders. So I wouldn't recommend taking shortcuts in that area.
