• Wireways


  • Designed to protect cables from environmental contaminants such as dust, dirt, oil, and water
  • Can be mounted to walls or ceilings, secured under flooring, or laid out in a hybrid design in unique cable management systems
  • Produced as a metallic or non-metallic trough with hinged or removable covers, so that the cables contained are well-protected but still accessible
• Metal Cutting Saw


  A kind of power tool which is typically used to cut hard materials. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel.
• Electric Drill


  A drill is an equipment primarily used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver, depending on application, secured by a chuck.
• Screwdriver


  Tools made of steel hardened and tempered at the tip used to loosen or tighten screws with slotted heads. They come in various sizes and shapes.
• File


  A tool used to remove fine amounts of material from a work piece. It is common in woodworking, metalworking and have variety of types ex. (flat, hand, square, round, half-round, triangular and knife edge.
• Open end wrench


  A hand tool with open jaws both end used to tighten and loosen the bolt and nut
• Hack Saw


  Originally and principally made for cutting metal, but can also cut various other materials, such as plastic and wood, electricians often use this to cut plastic pipe and plastic conduit.
• Spirit Level


  An instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb).
• Meter


  Commonly used by the electrician, an instrument for measuring the area or distance.
• 1. Square


  The main purpose is to ensure that the components are perpendicular or at right angles to each other. It also serves as a measurement ruler marked in inches, fractional inches, and sometimes centimeters and millimeters.
• 1. clamp


  Useful for clamping wood or metal; the hands crew is used for clamping wood objects at an angle. Most clamps have a face and an adjustable screw.
• Torque Wrench


  Tools designed to both fasten properly and to prevent over-tightening or under-tightening a bolt. Over-tightening can cause damage, and under-tightening can result in making the item structurally weak and potentially unsafe for use.
• Ratchet


  A mechanism that allows the handle to engage and tighten a fastener when swung in a clockwise direction but turn freely when swung counterclockwise.
• Offset Bolt Cutter


  A tool used to cut all sorts of metal. It cutters come with a variety of heads, with differently beveled blades that are designed to accommodate slightly different tasks.
• Use the right tools and right method to decrease amount of effort and to get a job done right without causing damage to either the equipment or to the surface being worked on.
