Athlon 1/4" 25mm Rod Clamp 360° Swivel Monitor Mount Adapter Black Knob

Rod clamp for 25 mm rails

This aluminium adapter clamps onto any rod between 24.9 mm and 25.5 mm and provides three 1/4" and one 3/8" threaded holes for mounting a monitor or accessory. The anodised black finish resists wear on professional rigs. A 360-degree swivel joint lets you position the screen at any angle without loosening the clamp. Two black knobs secure both the rod grip and the swivel tension.

Build quality and daily handling

Machined aluminium construction keeps the clamp rigid while the anodised surface prevents corrosion from frequent outdoor use. The dual-knob design allows one-handed tightening on set, and the four mixed threads mean you can attach most small monitors, lights or arms directly without extra plates. The 360-degree swivel rotates smoothly and locks solidly at the chosen orientation.

Upgrade path and fit

This adapter replaces fixed-angle rod blocks that force you to reposition the entire rail to change the viewing angle. It is worth adding when your current mount lacks 3/8" threads or cannot swing a monitor fully around for low-mode or client-viewing positions. Videographers who need a lighter or more compact clamp may find the aluminium body larger than minimalist carbon-fibre alternatives.
