I thought I would contact you about your (Telajack jack post) product. I like the system very well - it saved me about 4 hours on labor. The product is very well made.  Everyone that has seen them has asked about them, and I have given out your information to several people. One of the sales representatives was on the site the day of the set and was very impressed.  The homeowner likes the fact that, because of the size of the columns, he can later frame around them and totally conceal them. I will be using your product again.

Remember to measure from floor to rim joist on modular homes, and subtract 4 inches in order to get the full adjustment of the jack post. Always keep jack posts in an upright position, and check for plumb. Holes have been added in the top plate to accommodate 3/8' and 1 1/2" lag bolts. Bottom plates can be installed using 3/8" anchors if desired, or you have leveling lines to set in concrete footings.
