Quick answer

The SimXPro 4x Corner Bracket 4040 Aluminium is a four-piece set of 4040-profile corner brackets for sim racing cockpit builds. It fits standard 4040 aluminium profile joints; check your bolt and slot sizes before ordering, because the catalog does not list bolt dimensions or load ratings.

What the catalog does and does not confirm

The product listing confirms a four-piece corner bracket set for 4040 aluminium profile, intended for cockpit and rig builds. It does not publish bracket thickness, hole diameter, bolt grade, or load capacity. Treat those as unknowns and verify them against your own profile and hardware rather than assuming a spec.

That matters most on high-stress joints such as wheel deck uprights and pedal plate corners, where an undersized bolt or thin bracket can flex. If your build relies on a published load figure, ask the store before ordering.

Where one set is enough, and where it is not

Four brackets cover a simple two-profile corner, such as a single upright meeting a base rail. A full cockpit frame usually needs several sets because each corner, plus any mid-span reinforcement, consumes brackets. Count joints on your plan before checkout so you do not stall mid-build.

The catalog price of USD 7.23 against a comparison price of USD 11.12 makes a spare set inexpensive insurance, but the listing gives no quantity discount, so buy to your joint count rather than stockpiling.

Fitment questions answered

Will these fit my 4040 profile?

They are made for 4040 aluminium profile, so they match the slot size of standard 4040 extrusion. They are not intended for 4080, 3030, or other series; check the profile marking on your rig before buying.

Which bolts and T-nuts do I need?

The catalog does not specify bolt size or thread, so match hardware to your profile's slot and the bracket's hole diameter. Test-fit one bracket with a known bolt before committing to a full set. Buy hardware after the brackets arrive so you can measure the holes.

How do I align the bracket in the slot?

Seat the bracket square against both profile faces, slide the T-nut into the slot, and tighten gradually while checking square. Tighten one bolt partway, square the joint, then torque the rest evenly to avoid pulling the bracket out of alignment.

Can I use them for a wheel deck or pedal plate?

They are listed for cockpit and rig builds generally, but no load rating is published. For heavy wheel bases or load-cell pedals, use them as part of a braced joint rather than the only connection, and add profile reinforcement where the plan allows.

What is not in the specs?

Bracket thickness, hole diameter, bolt grade, finish, and load capacity are absent from the listing. If any of those decides your purchase, confirm with the store first; otherwise rely on test-fitting before final assembly.
