Installing Telajack jack posts to lift, level, support, or reinforce is simple.
Step 1: Measure support distance from floor to rim joist, subtracting 4" for top plate and threaded rod.
Step 2: If square tubing is not pre-cut to length, cut 4" shorter than total support height.
Step 3: Set base plate position and place square tubing in base plate.
Step 4: Place top cap on tubing, and srew threaded rod until it stops.
Step 5: Place hex nut on threaded rod, and add top plate and turn until tight.
Step 6: Ajdust hex nut on threaded rod to lock against top plate
Installation example: load bearing wall support and leveling
1. Double top plate construction
2. Telajack plate fastened with 3/8 x 1 1/2" lag bolts (2)
3. Threaded rod enables leveling to the hundredth of an inch over a 4" range
4. Strong top cap with deep cup to fully support square tubing
5. Square steel tubing can be cut to length on-site or pre-cut at the shop
6. Three fastening options:
- 3/8" x 1 1/2" lag bolts (2)
- 3/8" anchors (2) for "on-slab" installation
- 5/8" anchor for "on-slab" and foundation installation

INSTALLER WARNING:
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.
