PRECAUTIONS

This seatbelt kit has been rigorously tested by an independent laboratory to meet or 
exceed Federal Motor Vehicle Safety Standards (FMVSS) #208, #209, #302. 

Legal Disclosure

RetroBelt USA, LLC, or its subsidiaries assume no responsibility for proper or improper 
installation. Every attempt has been made to make this user’s manual as informative 
as possible. This manual may be updated from time to time. The retrofitting steps in 
this manual should only be performed by a professional installer to ensure that the 
installation is as safe as possible.

Government Regulations

All US passenger cars manufactured after 1961 have seatbelt anchor points for at 
least two lap belts in the front seat area. Since January 1, 1968, vehicle manufacturers 
have been required to install lap belt anchor points for each front and rear seating 
position as well as upper torso belt anchor points at each forward facing outboard 
seating position. On January 1, 1972, this requirement became effective for trucks. 

Warnings

Always use factory fittings added by the manufacturer whenever possible. 

When using the vehicle manufacturer’s threaded floor fittings, it is important that all 
full threads be engaged to obtain maximum strength of the anchor point. 

Seatbelts should NEVER be attached to the seat unless the vehicle manufacturer 
specifically designed the seats and seat mounting systems to withstand seatbelt 
assembly loads.

When drilling, make sure you don’t drill through the fuel lines, exhaust system, gas 
tank, brake lines, or electrical wiring.

Be certain that the area you plan to install your anchor mount to is strong enough 
before installing your anchor point. 

Always reinforce the anchor points to ensure the safety of the driver and passengers.

Some installations may require modification to the chassis, frame, or interior to 
allow for safe installation of an anchor point. This should only be attempted by a 
professional installer. 

If you are reusing existing anchor points, make sure you inspect them for cracks, rust, 
or other weaknesses. Do not reuse them if they are damaged in any way.
