Product Description
Sometimes the only thing standing between you and a good seat belt installation is a few inches. The anchor point is solid, but it puts the buckle too low, too far back or too close to the seat cushion. The Seatbelt Planet 6" Flat Bracket is a simple straight extension that moves the belt's attachment point to where it needs to be.
Specifications
Seatbelt Planet describes this part as a 6" straight flat extension bracket. Its listed specifications are:
- Type: straight, flat extension bracket
- Length: 6 inches from center hole to center hole
- Hole size: 0.520 inch
- Brand: Seatbelt Planet
The 0.520 inch holes are sized for the larger bolts used in seat belt installations. Seatbelt Planet notes elsewhere that its anchor holes in this range accept 7/16", 1/2" or 12mm bolts, so check that your hardware matches.
Common Uses
A flat bracket is the simplest way to extend an anchor point without changing its angle. Owners and builders use it to:
- Raise a buckle so it sits above a thick seat cushion or console
- Bring a buckle forward so it is easier to reach
- Clear a seat track, riser or bracket that would otherwise block the belt end
- Add length on one side of a lap belt when a seat has been moved or replaced
Flat, Angled or Double Bend?
Seatbelt Planet makes several extension brackets. A flat bracket like this one is the right choice when the anchor point is in the correct plane and only needs to move a set distance. If the belt needs to change direction, an angle bracket works better. If the anchor is recessed or obstructed, a double bend bracket provides an offset. We carry all three, so you can choose the shape that fits your installation.
Ordering
Each bracket extends one anchor point. If you are working on both sides of a seat, or on several seats, use the quantity menu to order up to four at once so everything matches.
Hardware and Mounting
A bracket is only part of the installation. Use proper seat belt bolts of the correct grade and thread, along with lock washers or locking nuts. Where the floor or panel metal is thin, back it with a reinforcement plate. Make sure the mounting surface is solid and free of rust. A strong bracket bolted to weak metal will not provide the protection a seat belt is meant to deliver.
Fitting Tips
Before you tighten anything, sit in the seat and fasten the belt. The lap portion should lie low across the hips. Check that the bracket and belt end clear the seat track through its full range of travel, and that nothing rubs on wiring, fuel lines or brake lines. Tighten all bolts securely and check them again after a short drive. If you are not sure an anchor location is strong enough, ask a qualified shop to inspect it.
A small bracket can make a big difference to comfort and safety. Moving a buckle just a few inches often turns an awkward belt into one that is easy to use every day.
