Has anyone ever herd of a molly jack for under house holding level.?

Question

after jacking up the house the molly jack (screw jack) is used to hold the position. I can't find any or anyone that what they are. I used them in New Hamphsire and got them at Home Depot. I am In New Mexico now and can't find any.

Answer 1

There seems to be some variation in terminology, but I just bought one of these last weekend from Home Depot. It was called a "Jack Post" and cost me $24.87. Hard to imagine that they wouldn't carry them at home improvement stores in New Mexico.


You shouldn't need a concrete-filled post unless you're dealing with very large loads.

One detail that people often overlook: make sure not to raise the jack more than 1/2 turn per week. It's very tempting to accelerate this (I had an insane urge today to just go turn it "one more half turn"), but you want to give the structure time to adjust to being lifted. (Think about how you stretch your muscles--gradual and firm, not just a sharp jerk.)

Good luck with it!

Answer 2

That is kinda like a haunted trailer. I suppose that's one of the reasons that when i was a kid I was never afraid of ghosts because we live in a modern house about that size and I figured ghosts haunted much nicer digs. With central heat and no chimney I never really believed that story about my mom leaving the back door unlocked for Santa. Oh well I suppose that's one of the trade-offs or maybe I should say advantages of living the the modern world.

Answer 3

Pretty standard item. Home Depot, Lowes, Menards, or any home improvement chain should have them. You can also check with a good hardware store.

Answer 4

I think you mean 'lally column.'

A concrete-filled steel tube, set into a specially-designed concrete footing, with a steel saddle at the top to hold the floor beam.
