Wire arm construction provides superior torsional rigidity. 'No snag' head prevents sheets becoming trapped under wires. Delrin ball bearings ensure smooth rotation. Stainless steel balls bear vertical Load and virtually eliminate vertical play. With optional detent stop fitted the base rotates freely between 160 and 220 degrees. The detent prevents the base spinning to leeward when sheet load is released. Removable forward pin limits rotation to 220 degrees (pin must be pushed down fully).
