A portable safety rail system includes one or more railings inserted into one or more stackable rail bases. Each rail base can include a plurality of apertures for receiving end rail posts of railings through a raised hub defining an open region between the bottom of the hub and the surface on which the rail base rests. Each end rail post can have a stop flange that engages an upper surface of the hub when inserted therein and an aperture through the end portion that extends into the open region beneath the hub for receiving a pin to lock the post while allowing rotation of the post. The system can also include toe boards that are attached to railings with a mount having an aperture through which railings are extended, allowing the toe boards to also be rotated to be aligned with railings.

A magnetic umbrella swivel holder system comprising a swivel umbrella holder, further comprising an upper portion and a lower portion, wherein the upper portion is a first tube with a diameter sized to hold an umbrella pole, the lower portion is a second tube. Preferably, the upper portion is connected to the lower portion with a pivot device. A magnet is preferably removably attached to the lower portion using a fastener that threadably attaches to a receptacle fitted within the lower portion such that the magnet forms a bottom surface.

A support for installing a porch post comprises a body. The body includes a ground end and a post end opposite of the ground end. A base is disposed on the ground end of the body. Two or more sidewalls extend from the base toward the post end. One or more open cross-members extend between the two or more sidewalls. The ground end may include a ground surface comprising grippers or stanchions extending away from the ground surface for securing the support with the ground.

Provided is a utility support. The utility support may include a bottom base with a tapering side wall extending therefrom towards a top base. Additionally, the utility support may be hollow. Further, at least one of the side wall, the bottom base and the top base may be configured with at least one utility portion.

There is provided a structure support arrangement for supporting a structure, the structure support arrangement comprising: a body member; a nesting formation defined on the body member and configured to prevent lateral movement of the structure support arrangement in at least one transverse direction when the structure support arrangement is nested with a further structure support arrangement; and a post receiving formation defined on the body member and configured for receiving a support post to support the structure.

Disclosed is a rapidly deployable, above grade, low-thermal conducting, grillage-type foundation system made of composite materials, and erectable at or above grade for supporting structures like equipment shelters and communication masts. These units include generator sheds, communication shelters, fuel tanks, radio masts, and the like. The foundation system has one or more layers of beams laid at right angles to each other, and is used to disperse heavy point loads of a superstructure to an acceptable ground bearing pressure. Web stiffeners were affixed to foundation beams and vertical support members were fixed to the upper surface of the foundation beams, to stiffen the foundation and structure at every footing. The foundation is adapted to be installed with little site preparation, is easily transportable with a medium lift helicopter. Essentially, the foundation was engineered to only use steel in its assembly for the metal feet, angles, plates and the like.

A base for a subterranean fence post which includes a body with a ground-engaging surface and a mechanism for mounting a lower end of the fence post to the body wherein a footprint of the surface is sufficient to provide lateral support to maintain the post in an upright orientation and a mass of the body is sufficient to stabilize the upright post.

A portable lightning protection system including a multi-section conductive mast assembly including at least a base mast section and a top mast section; an air terminal attachable to the top mast section; and a base assembly attachable to the base mast section via a hinge assembly, wherein the hinge assembly may be configured to allow the base mast section to hinge relative to the base assembly. A catenary lightning protection system including at least two lightning protection systems, each lightning protection system may include a multi-section conductive mast assembly including at least a base mast section and a top mast section; an air terminal attachable to the top mast section; a base assembly attachable to the base mast section; and may further include a catenary wire connected between the at least two lightning protection systems.

A bracket has: a plate having bolt holes and a utility pole mount; a clamp secured to the plate, the clamp comprising cooperating screw pile shaft receiving parts having laterally extending flanges, the flanges having fastener receiving openings for securing the clamp around a screw pile. A combination has: a bracket; a utility pole extended from a ground surface, in which the plate is bolted to the utility pole through the bolt holes in the plate; and a screw pile fastened to the clamp and penetrating the ground surface.

The disclosed technology includes a universal tree stand for supporting trees with tree trunks of various sizes. The universal tree stand may include a clamping element to flexibly receive and secure tree trunks of different sizes. The universal tree stand may further include a fastening element that can tighten the grip of the clamping element around the tree trunk.
