Loctek D7L Single Monitor Gas Spring Arm

Overview

The Loctek D7L is a premium mid-range single monitor arm that bridges the gap between budget arms and flagship Ergotron models. It features a robust aluminum alloy construction with a reinforced gas spring supporting monitors up to 19.8 lbs (9 kg) and up to 35 inches. The D7L stands out for its exceptional 525 mm (20.7 in) reach — longer than the Ergotron LX — making it ideal for deep desks, floating monitor setups, or sit-stand desk workflows. With full articulation, tool-free installation, and adjustable gas spring tension, it delivers premium ergonomics at a mid-range price point. Available in black and silver finishes.
