The new Safety Hangers 8/8 and 8/6 are compatible with Lines 6 and 8 of the item MB Building Kit System. The entire guard panel can be fastened by a single person using a captive security fastening bolt. The guard panel is slotted into the lower hanger and then screwed to the profile groove via the upper Safety Hanger. The special security bolt can only be driven using a special tool and is held captive in the upper hanger. The entire hanger is also break-proof in crash scenarios, thus ensuring the protective enclosure is exceptionally safe. Another new feature is the sliding door with Security Limit Switch for protective enclosures. The door can be opened and closed in full compliance with machine design directives.
