What are Longitudinal and Lateral Stabilizer Devices and do I need them on my mobile home?
Longitudinal and lateral stabilizer devices prevent the home from moving when exposed to a strong wind on one end of the home.
Lateral devices prevent sideways movement which would cause the tie-down system to fail.
Strong winds from a hurricane or severe storm expose the sides of the mobile home structure to excessive lateral or longitudinal forces.
So What are My Stabilizer Options?
There are several answers to this question depending on where you have it located and whether your mobile home is new or used.
Homes installed prior to 1997 in Florida do not have the new systems installed.
New homes in Florida are required to have longitudinal stabilization but not necessarily specific devices.
There are alternate methods that are in use and that comply with the state requirements in Florida 15-c.
Used homes are required to have longitudinal devices or anchors attached when installed.
The type of stabilization will depend on the year of manufacture and whether side wall straps are installed.
According to Florida code stabilizer devices can only be installed on homes with sidewall straps attached every 5 foot 4 inches installed at the factory.
These sidewall straps which are then attached to galvanized anchors do not require stabilizer plates to be installed except at the location of the stabilizer device.
What about Used Homes being Reinstalled?
Used homes that do not meet this requirement all required 2 have longitudinal anchors and plates installed each side of the end of each “I” beam.
Gator clamps are used to connect straps to the beam. Each anchor requires a stabilizer plate.
Single wide mobile homes will require a total of 8 longitudinal anchors while a double-wide home will require 16 anchors to be installed.
New Home Systems.
Homes that have the required number of sidewall vertical ties need to have stabilizer devices installed.
Only devices manufactured to State requirements and appearing on the approved product list will be allowed.
When it Comes to Stabilizers Size Really Matters.
The number and location of these devices will depend upon 3 things:
- Firstly the length of the home.
- Secondly the width of the home. (number of sections)
- Thirdly the pitch of the roof.
As an example double wide mobile homes less than 52 feet will require four systems with lateral arms. However, an 80 foot double wide with a 6-12 roof pitch will require 8 devices in Florida.
The addition of longitudinal and lateral stabilizer devices will improve any mobile homes ability to withstand storm conditions.
