Key Features
Sliding Installation
Insert from the profile end and slide to any position along the T-slot. The rectangular body provides smooth, controlled movement for precise positioning before tightening.
EU Profile Compatible
Designed for EU standard T-slot profiles from 20 to 50 series (206, 308, 408, 4010/4510/5010), covering the most widely used EU profile dimensions in industrial applications.
Precise Positioning
Slide to exact position before tightening, enabling precise alignment of brackets, panels, and accessories on aluminum profile frames.
Compact Low-Profile Design
The flat rectangular body sits flush within the T-slot channel, maintaining a clean frame exterior without protruding hardware.
