Features
- Dovetail rail mounting: The rail mounts to the BASE Rack's dovetail system, which makes fitting simple and keeps it secure.
- Keeps cargo in place: The rail gives the load a barrier to sit against, so gear is less likely to shift or slide off over rough ground.
- Open-rear 3/4 design: Front and side rails hold the load while the rear stays open for loading.
- Made for demanding off-road use: ARB built the rail for dependable use in tough off-road conditions.
- Matches the BASE Rack profile: Its slim, strong rails are drawn to sit with the low BASE Rack deck.
- Suits a wide range of loads: The rail helps secure many kinds of loads on the platform.

About ARB
ARB began in Melbourne, Australia, in 1975, when founder Tony Brown started building bull bars for four wheel drives heading into the outback. Fifty years on, ARB designs and tests its own 4x4 equipment, from bumpers, winches and recovery gear to Air Locker differentials, fridges and camping kit.
In North America, ARB products are supported by ARB's US office, Air Locker Inc., in Auburn, Washington, which administers the warranty for products bought here.

Frequently Asked Questions
Does it fit the 72" x 45" platform?
No. It is sized for the 51" wide 72" rack (1770030).
Can I add a rear rail later?
ARB offers a full rail as a separate part; this listing is the three quarter style only.
Does the rail fit my BASE Rack?
Each ARB guard rail is made for one BASE Rack size. Match the size on this page to your platform's size, not to the vehicle.
How does it attach?
It clamps into the BASE Rack's dovetail channel with cast aluminum upright clamps and uses the rack's corner fixing points. ARB supplies Torx fasteners with nyloc nuts.
Can I change the rail later?
Yes. Guard rails come off the dovetail channel, so you can move from one style to another as your loads change.
What warranty applies?
ARB covers BASE Rack guard rails for 3 years with unlimited miles against defects in materials and workmanship.
