## Abstract

Aspects of the disclosure are directed to a safety adapter that is removably and replaceably securable to a hollow lock nut hydraulic cylinder that includes a threaded collar. The safety adapter may comprise a cylindrical sidewall having a distal axial end and proximate axial end, that at the distal axial end includes a top surface having a center through hole and at the proximate axial end includes a sidewall threaded surface on an interior surface of the cylindrical sidewall configured and arranged to engage with the threaded collar.

## Claims

### Claim 1

A safety adapter that is removably and replaceably securable to a hollow lock nut hydraulic cylinder that includes a threaded collar, the safety adapter comprising:
a cylindrical sidewall having a distal axial end and a proximate axial end, that at the distal axial end includes a top surface having a center through hole and at the proximate axial end includes a sidewall threaded surface on an interior surface of the cylindrical sidewall configured and arranged to engage with the threaded collar.

### Claim 2 (depends on 1)

The safety adapter of claim 1, where the cylindrical sidewall is aluminum.

### Claim 3 (depends on 1)

The safety adapter of claim 1, where the safety adapter is a synthetic fiber.

### Claim 4 (depends on 1)

The safety adapter of claim 1, where the cylindrical sidewall has a central region that is tapered radially inward with respect to the distal axial end and the proximate axial end.

### Claim 5 (depends on 1)

The safety adapter of claim 1, where distal axial end and the proximate axial end taper bulbously outward from a central region of the cylindrical sidewall.

### Claim 6

A safety adapter, comprising:
a cylindrical sidewall having a distal axial end and a proximate axial end, that at the distal axial end includes a top surface having a center through hole and at the proximate axial end includes a sidewall threaded surface on an interior surface of the cylindrical sidewall, where the cylindrical sidewall has a central region that is tapered radially inward with respect to the distal axial end and the proximate axial end.
