Anchor screw bolted on to standard economy panel Safe loading capacities based on load factor of 1,5:1 on ultimate pull-out values CAUTION: Although graph is based on actual tests, it is given as a general guide only. Where warranted a greater safety factor should be used

The anchor screws are cast in and are easily removed using an extractor tool.
