Requirements for sockets, screw-in fittings and step irons to provide access for persons who normally fit their own ladders.

This British Standard specifies requirements for the following groups of fittings to provide means of access for inspection and maintenance by steeplejacks and similar trades who normally fit their own ladders.

1. Sockets for embedding in concrete a brickwork.
2. Cappings for sockets.
3. Screw-in fittings, i.e. screw-in hooks and screw-in eyes.

The requirements specified for the fittings are in respect of materials, workman ship, design, construction and dimensions.

General recommendations on the methods of use of access fittings are given in Appendix A.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
