K2 XS Module Centre Clamp Black Anodised 30mm Frames
Product details
A centre clamp set for the thinnest frames on the market: 30 mm, which is where most of the current all-black modules sit. Black anodised, so on a black-framed panel the fixing disappears into the array.
The XS is a single-size clamp, not an adjustable one. It fits 30 mm and nothing else – which is what keeps it small enough to stay out of sight.
Check the frame first
Take the frame height from the module datasheet rather than assuming. A 30 mm clamp on a 35 mm frame will not close, and on a 30 mm frame a wider clamp leaves the panel loose. K2 also state that this clamp is not compatible with the K2 Dome 6 system, which uses its own DomeClamp range.
Finish
Aluminium EN AW 6063 T66 with stainless steel and TPE/PA. K2 note that the anodising may show slight scratches from packaging and transport – cosmetic, on a part that ends up between two panels.

Questions on the XS centre clamp
Only if the frame is 30 mm deep. That figure is on the module datasheet, usually as the frame height or module thickness.
Centre clamps sit between two panels and hold both. End clamps finish each end of a row. A row of six panels takes five centre clamps and two end clamps.
No. K2 state it is not compatible with Dome 6, which has its own DomeClamp range – linked above.
The T-bolt and nut are ordered separately and are linked above.
