Connector clamp
In a tree lightning protection system, a cast or stamped connector that uses crimped, fingerlike projections to secure conductor connections in an end to end, side-by-side, or Y configuration
Crimp-type connector
Brace for him by threading a lag threaded screw ride directly into a limb, leader, or trunk but not through the side opposite the installation
Dead end brace
Manufactured wire wrap design to form a termination in the end of a 1 x 7 left hand lay cable
Dead-end grips (tree grips)
Anchors or braces that are threaded directly into the tree but not through the side opposite the installation; dead-end hardware includes, but is not limited to, lag hooks, lag eyes, and lag threaded screw rods
Dead-end hardware
In tree support systems, simple tree cabling system trying to branches are leaders with a single cable
Direct cable system
Any of several cabling systems that utilize elastic materials (usually rope or various constructions) for three support systems
Dynamic cable system
In tree support systems, type of 7-strand steel cable, often use to cable trees; stronger but less flexible than common grade cable; must be terminated with dead-end tree grips or terminal fasteners
Extra-high strength (EHS) cable
Drop-forged, closed-eye bolt, used to anchor cables to a tree and he through-fastened system
Eye bolt
In cabling, a closed termination loop, hand forged in common-grade cable by wrapping the successive strands back up on the standing part to attach the cable to anchor hardware
Eye splice
To create a path for an electric current to reach the earth
Ground
In a tree lightning protection system, a copper plate used to for me ground terminal in shallow soil’s
Ground plate
Metal rod used in grounding a lightning protection system
Ground rod
The portion of a lightning protection system-such as a radial conductor, ground rod, or ground plate that is installed for the purpose of providing electrical contact with the earth
Ground terminal
Electrically connected to the earth, providing a path for the flow of electricity to prevent accidental energizing
Grounded
A steel or synthetic fiber cable between a tree or branch with an external anchor (another tree, the ground, or other fixed object) to provide supplemental support.
Guying
Devices to class and hold common grade cable
Haven Gripe
Birthday becomes in bedded in the union between branch in trunk or between codominant Stems; lax would connections, Resulting in a weak structure
Included dark
Lag-threaded, closed-eye cable anchor used for dead-end systems
Lag eye
Lag-threaded, J-shaped cable anchor
Lag hook (J-hook)
Cable anchor or bracing rod with a coarse thread pattern; typically screwed into a pre-drilled hole that is smaller in diameter than the anchor a rod a rod
Lag-threaded
Fine thread pattern on hardware, used to the nut and washer and installed three pre-drilled hole that is larger in diameter than the hardware being installed
Machine threaded
System by which effort or force can be multiplied
Mechanical advantage
The act of bending, rounding, or flattening the end of through hardware for the purpose of preventing a nut from backing off
