A safety rail, comprising:
- a body disposed on first and second adjustable boots adapted to secure the safety rail to an excavation support structure, the body comprising a lower rail connected to the first and second adjustable boots,
- wherein the first adjustable boot and the second adjustable boot each comprises:
- a first member having a first jaw disposed thereon;
- a second member having a second jaw disposed thereon;
- a first tightener disposed through the first member and connected to the second member,
- wherein the first tightener is adapted to move the first and second jaws toward one another when actuated in a first direction and away from one another when actuated in a second direction,
- a second tightener is disposed through the first jaw,
- wherein the first member comprises a connector base, and wherein the connector base and the first jaw are both disposed on one or more supports, and
- wherein the second member comprises a slider and the second jaw, the slider being adapted to fit into the first member between the connector base and the first jaw.
