Sim Rig Keyboard Tray: 40 or 50 cm Swivel Arm?

The right keyboard tray depends on your keyboard and the space around your rig. Grizzly offers a compact set with a 400 × 200 mm tray and a 40 cm swivel arm profile, plus an XL set with a 500 × 200 mm tray and a 50 cm swivel arm profile. Both are specified for mounting to 40 mm aluminium profiles, I-type / slot 8.

Before ordering: measure your keyboard and rig

Start by measuring your keyboard’s width and depth. Compare both dimensions with the tray surface. The extra width of the XL set may matter if your keyboard does not fit fully on the compact tray; both versions have the same depth.

Then sit in your usual driving position. Check where you want to reach the keyboard and where the tray can swing out of the way. Allow for the seat, steering wheel, shifter, cables and the space beside your rig. What matters is a usable position and enough swing clearance in your actual setup.

The 40 and 50 cm measurements refer to the arm profile length. According to the product specifications, the overall length is approximately 7 cm longer. Do not use the profile length as the exact measurement of the complete assembly.

Which profile do I need?

Both sets specify 40 mm aluminium profiles with I-type / slot 8. Check these details against your rig. If you have a different profile type or are unsure of the slot size, clarify the mounting before buying. The visible profile width alone does not confirm a suitable fit.

What is included in the set?

The compact set includes the keyboard tray and swivel arm with a 40 cm profile. The XL set includes the XL keyboard tray and swivel arm with a 50 cm profile. The keyboard shown in the photos is not included. The product specifications offer black or aluminium finishes for the profile and joint.
