Claim 10

A safety system for a pallet rack having a plurality of upright posts supporting horizontally disposed load beams comprising at least one offset means for offsetting the effective attachment position of a post, said offset means comprising: an elongated tubular member having two pairs of opposed sides, said opposed sides defining a multiplicity of aligned pairs of apertures; a mounting plate mounted at one end of said tubular member, the plane of said plate being perpendicular to the central longitudinal axis of said tubular member, said plate defining two aligned pairs of openings; mounting means for mounting at least one mounting plate to an upright support post for generally horizontal projection of said tubular member from said post; and cable means comprising a cable and connecting means for connecting said cable to said offset means through selected aligned pairs of apertures, so that said cable is suspended in offset relationship to said post.

Claim 11

A safety system for a pallet rack having a plurality of upright posts supporting horizontally disposed load beams comprising at least one offset means for offsetting the effective attachment position of a post, said offset means comprising: an elongated tubular member having two pairs of opposed sides, said opposed sides defining a multiplicity of aligned pairs of apertures; a mounting plate mounted at one end of said tubular member, the plane of said plate being perpendicular to the central longitudinal axis of said tubular member, said plate defining two aligned pairs of openings; mounting means for mounting at least one mounting plate to an upright support post for generally horizontal projection of said tubular member from said post; and cable means comprising a cable and connecting means for connecting said cable to said offset means through selected aligned pairs of apertures, so that said cable is suspended in offset relationship to said post.

Claim 12

The safety system of claim 9 comprising four offset means, said cable means suspended from said offset means so as to generally form a cable framework offset from said support posts.

Claim 13

The safety system of claim 9 wherein said opposed sides define an aligned set of openings having an enlarged diameter and an aligned set of openings having a reduced diameter.

Claim 14

The safety system of claim 11 further comprising adjustable brace means for bracing at least one offset means and brace connecting means for connecting said adjustable brace means to a said offset means,

Claim 15

The safety system of claim 12 wherein said brace connecting means connects through said enlarged openings.

Claim 16

The safety system of claim 12 wherein said adjustable brace means comprises a pair of elongated tubular members.

Claim 17

A safety system for a pallet rack having a plurality of upright posts supporting horizontally disposed load beams comprising: at least one extension means for extending the effective vertical extent of a post, said extension means comprising: a mounting tube; a pair of longitudinally spaced mounting plates fixably mounted to said tube; an extender boom having an extension end and slidably receivable in said tube and longitudinally positionable at a plurality of positions therewith; adjustment means for adjustably fixing the distance of said extension end from said mounting tube; mounting means for mounting said tube mounting plates to rack posts so that said extension ends are disposed above said posts; an offset member mounted to each said boom for generally transverse extension thereto, said at least one offset member defining a plurality of aligned openings; and at least one expandable brace means connecting an offset member for bracing said offset member and comprising a pair of tubular members which are slidably positionable for adjusting the length of said brace means to thereby brace said offset member at a pre-determined position.

Claim 18

A safety system for a pallet rack having a plurality of upright posts supporting horizontally disposed load beams comprising: at least one extension means for extending the effective vertical extent of a post, said extension means comprising: a mounting tube; a pair of longitudinally spaced mounting plates fixably mounted to said tube; an extender boom having an extension end and slidably receivable in said tube and longitudinally positionable at a plurality of positions therewith; adjustment means for adjustably fixing the distance of said extension end from said mounting tube; mounting means for mounting said tube mounting plates to rack posts so that said extension ends are disposed above said posts; an offset member mounted to each said boom for generally transverse extension thereto, said at least one offset member defining a plurality of aligned openings; and at least one expandable brace means connecting an offset member for bracing said offset member and comprising a pair of tubular members which are slidably positionable for adjusting the length of said brace means to thereby brace said offset member at a pre-determined position.

Claim 19

The safety system of claim 15 comprising two extensions means, two offset members and two expandable brace means.

Claim 20

The safety system of claim 16 further comprising two lower offset members mountable to two support posts, each said lower offset member defining a plurality of openings.

Claim 21
