A lighting module assembly, including a module base and module cover housing a light source, and having latches sized and spaced so as to mate with the channels of the module base, each latch having a latch tab at a distal end of the latch. A locking unit connects the module cover and the module base together. The locking unit is formed of a springy material and includes two locking bodies and a ramped tang extending from the bottom of the locking body, and a pair of latch members, one mounted on each side of the ramped tang. The module cover includes a reflector portion for receiving light from the light source. The assembly may be provided with a tool with a plurality of prongs, connected by a handle and which, when inserted, engage the ramped tang and move the latches, to release the lighting module from the support base.

A railing bracket system includes a cup that has a cup bottom wall and two opposed cup side walls. The cup is adapted to receive an end of a railing member. A cap has a first cap wall disposed between two opposed cap side walls and a tab extending from at least one side wall. The cap is adapted to cover the cup.

Techniques and devices are disclosed for fabrication layout device. The device includes a table with a work surface. The work surface being a continuous surface and configured to support a plurality of railing pieces for fabrication of a railing assembly. The device further includes a beam located above the work surface. The beam is operatively coupled to the table, such that the beam moves relative to the work surface in a first direction. Attached to the beam is an ink dispenser. The ink dispenser is configured to move along the beam in a second direction different from the first direction. The ink dispenser is further configured to dispense ink onto the work surface of the table in the form of a pattern of the railing assembly. Railing pieces are positioned on the pattern so that they can be assembled to one another.

A railing bracket system includes a cup that has a cup bottom wall and two opposed cup side walls. The cup is adapted to receive an end of a railing member. A cap has a first cap wall disposed between two opposed cap side walls and a tab extending from at least one side wall. The cap is adapted to cover the cup.

In a railing system comprising a railing panel frontage which extends continuously along the course of the railing and consists of a plurality of mutually adjacent railing panels, in order to increase an additional resistance and security against destruction, an additional securing element, which, given a properly erected railing, extends between a handrail profile, resting on the railing panels, and a structural body or a holding profile disposed on the structural body and connects the handrail profile to the structural body or the holding profile, is provided.

An articulated attachment assembly and a rail system and method of installation for rail installations in which there is an elevational change between vertical supports, in which the articulated attachment assembly eliminates the need for field mitering of components and provides instead a first articulated hinge assembly having a first mounting block to be attached to the first support, a second mounting block to be attached to the first rail connection block, and a hinge member to couple the second mounting block to the first mounting block and enable the second mounting block, the first rail connection block, and the rail to pivot together relative to the first mounting block and the first support.

A modular guardrail system relates to a set of interconnected beams that each fit into pairs of detachable bases, thus allowing for the creation, adjustment, and removal of a variety of configurations of temporary fence-style barriers. Each guardrail section may include two vertical posts, one on each end of each guardrail section, connected by a set of horizontal beams and, in some cases, a horizontal toeplate. Adjacent guardrail sections share a common base, thus allowing for the chain assembly of an extended barrier. The base that connects to the guardrail sections may include several vertically-oriented brackets that may slide into the different guardrail posts. The placement of the vertical brackets upon the base is selected so that each of the attached guardrail sections can be arranged independently of one another in any direction. The vertical brackets may be rotatably attached, thereby allowing for more flexible arrangements of the guardrail sections.

A telescoping rail assembly for a roof hatch includes a bracket configured to couple to the roof hatch, where the roof hatch is configured to provide access to a roof of a building, a post coupled to the bracket and configured to extend from the roof hatch and outward from the roof, and a telescoping rail having a first portion and a second portion, where the first portion and the second portion are slidably adjustable with respect to one another, and where the telescoping rail is disposed along a portion of a perimeter of the roof hatch to enable the telescoping rail assembly to enclose an area that includes the roof hatch.

A vertically adjustable railing having first and second elongate balusters each with a first and second ends, the balusters having a first connection elements at their first ends and second connection elements along their length. An elongate handrail is pivotally connected at its first end to the first connection element of the first baluster and pivotally connected at its second end to the first connection element of the second baluster. An elongate lower rail having a first end and a second end is pivotally connected at its first end to the second connection element of the first baluster and pivotally connected at its second end to the second connection element of the second baluster. A distance between the first end and the second connection element of the first baluster is greater than the distance between the first end and the second connection element of the second baluster.

A cable railing assembly having a plurality of posts, an expandable cable guide assembly, and a tensioning apparatus, and a method of assembling the cable railing assembly. The expandable cable guide assembly includes a pair of cable braces with a cable extending in a serpentine fashion between the cable braces. The tensioning apparatus includes a tensioner base, a tensioner body, a compression spring positioned between the tensioner base and the tensioner body, a movable carriage slidably mounted adjacent the tensioner body and comprising a cable clamp for gripping the cable, and a threaded adjuster secured to the body and operative for moving the movable carriage along the body.
