I have an aluminum extension ladder. Both rung locks are broken and I need new ones. Our local ladder supply said if it is a Louisville or Werner they can get parts. However, this ladder is over 30 years old and there is no ID on it. I have been to the Werner site and the Lynn site and the rung locks they show are not mine. I can take a photo of one of the locks and send it to you, or anyone you suggest, to see if I can locate replacement parts. Any ideas?

I'm in a similar boat except only one is broken. How did you make out?

No luck finding them. All potential sources wanted ladder manufacyurere name, model number, but this was gone from the ladder. So I made two of my own. Not really like the rung locks you normally see but they work well. Will take a photo and send it to you. What is your email?

Thanks. My email: hclb@optonline.net. I think I bought the 40" ladder from Montgomery Ward about 35 years ago. No marking whatsover.

What I did was to fashion a pair of wooden blocks that sit on any rung I want to use as the bottom of the extension piece. I shaped them to fit inside the rails of the ladder which sits on the ground, then they rest against the rung which I want, and act as a stop to the bottom of the rail of the moving ladder. Will take a photo and send to you.

Glendot, I'd like very much to see your photo(s) of how you solved your problem.

thanks

Here are a couple of photos. As you will see they are not very sophisticated, just something I cobbled up in desperation. However I have used them many times and they seem to hold up quite well with my 250 pounds. I designed in a slot to put in a tie down but I don't use it. My weight alone, together with the ladder edges, seem to hold them in place quite well. Note there is a left and a right one. Good luck.
Whoops, just noticed there is a limit of one photo per post. I will do a second post to show how they go on the ladder

Here is the picture of the rung locks in place. They do not attach to the ladder, just sit there when in use.When not in use, I store them seoparately.

Thanks a lot. I would have never thought of this method.

I drove all over the place....Menards Home Depot, Lowes, nobody carries parts for extension ladders. several hundred for the ladder and on a cold day the rung lock snaps back to lock the ladder and "snap" it breaks making the ladder (at the very least) or unuseable. I found this site that carries them, but they ain't cheap...$68.00 each. I'm gonna take the old one off and make a clay mold and see it I can't melt some aluminum and make a repalcement. will post pics in about a week to 10 days... today is Sunday Jan 7th 07
