INSTALLATION INFORMATION Anchor Installation Electric Drive Machine Installation 1. Position anchor at a slight back angle (10˚) so that when fully installed, the anchor head will be inside any skirting or side wall. 2. Install anchor to +/- 2/3 depth, then install stabilizer vertically, within 3”-4” of anchor shaft, parallel to wall of home. 3. Fully drive anchor, attach strap (see proper strap tensioning), and pretension strap to pull anchor rod against the stabilizer plate. 1.
INSTALLATION INFORMATION Certified Galvanized Strapping* Strap Attachment The HUD Code requires that certified strapping must meet ASTM specifications, have a minimum (0.30 oz. per square foot) galvanized coating and must be marked every 5 ft.. Tie Down strapping is marked every 12 in. * Available with G60 or G120 galvanized coatings. One crimp seal is used when strap is attached to a sidewall bracket or a strap connector.
INSTALLATION INFORMATION Cross Drive Rock Anchor - MRA Strap Buckle - MBU Engineered for installation into solid rock within 1 in. from bottom of the anchor base. Exact alignment is achieved with the swivel tensioning head. • Thread length of frame tie strap through strap buckle as shown. • Drill 5/8" diameter hole 5-1/2" deep in center of anchor location. Insert pilot stud into hole. • Next, thread long end of strap between frame and floor of home.
INSTALLATION INFORMATION 1. Refer to local, State, and Federal regulations prior to installation in order to assure compliance. 2. Soil Test Probe the anchor location prior to installation in order to match the soil classification with the proper anchor/stabilizer combination. 3. Install tested and approved Tie Down Engineering anchor products. Swivel Strap Connector (Best Option) 1. Frame ties attach to the beam with a swivel frame connector. This method provides the strongest and safest connection. 2.
INSTALLATION INFORMATION Patio Slab Anchor Concrete Anchor This anchor is designed to be inserted through a 3/4" hole drilled or formed into an existing concrete slab. The MIJ2 is designed to be installed into a concrete slab at the time the concrete is being poured. • Concrete must be a 2500 PSI minimum slab with 4" minimum thickness and 6/6 x 10/10 wire mesh or fiber mesh installed. • Concrete must be a 2500 PSI minimum slab with 4" minimum thickness.
Soil Classification Chart Ground anchors are designed for different soil classifications: longer models for loose soils, shorter models for harder soils. Prior to installing any ground anchor model, the soil must be tested (with a Soil Test Probe) in order to match approved ground anchor model with site soil class. WARNING: Before ground anchor installation, determine that the anchor locations around home will not be close to any underground electrical cables, water lines or sewer piping.
