Here are some more information for Copper Lock:
In the deep South, Mid West and Northern New England, sheet metal and corrugated steel roofing systems were used solely for the industrial, commercial and institutional use in the past. Today, standing seam metal roofing has evolved to become a statement of the modern architecture. It has become a premium choice of many people wanting to have a reliable and long lasting roof protecting their homes. Once standing seam roof has been correctly installed, it becomes virtually unnecessary to maintain it. Standing seam, will more often than not last a full lifetime. These types of roofing panels are available in many materials such as aluminum, zinc and aluminum coated steel, zinc, and copper, and come coated with Cool roof rated colors, designs and styles.
Do it your self or Not
Installing sheet roofing system is not exactly a do it yourself type of project. It requires the experience and mastery of knowing how to install sheet metal panels on your roof, which takes special training and knowledge that cannot be learned from just reading the instruction manual. This type of experience can only be acquired by doing the actual roof installations and working with sheet metal for some time. Below, I am going to explain a few basic principles just to give you a better idea of some of the steps involved in the installation of this system, but first lets try to better understand the locking mechanism called the seam.
More about the seam system
Each time there is a joining, that particular area is raised creating the rib that is called the seam. It is this that connects the sheet roofing panels together and causes the water to run off in a safe fashion without dripping amongst the panels. Standard seam roofing panels, can be ordered if this is going to be a do-it-yourself job. It is custom ordered and arrives with full instructions. Hidden fasteners are used to join the metal panels together.
Installing roofing felt before sheet roofing panels get installed
In order to block out moisture you need to have a vapor barrier installed underneath standing seam metal roof. These are normally placed over the structure before the metal sheet panels get installed, and are usually made from plastic or foil sheets. This creates a protective lining. This will stop the vapor from rising to the top and causing the structure to rot. It is essential to place this on all kinds of roofs, before installing the actual roofing system. be it asphalt or metal. Aside from the preservation of the material, you can also keep out extreme weather conditions to some degree by installing ice and water on the eaves of the roof, before installing vertical sheet metal panels for your roof.
When tearing off the existing roof, all the water damaged boards and plywood need to be replaced. The walls must be dry and debris free. The water and vapor barrier must then be nailed or stapled about two feet apart in order to secure it safely.
Installation basics:
In order for the metal roofing panels to be installed, you need to secure and connect the panels that are vertical and have a locking mechanism on the side of the panels called the seam. Standing seam metal roofing panels get secured to the eave flashing with special locking mechanism. Then, vertical panels are secured by concealed fasteners along the side of each panel every 12 inches on center. Securing with the concealed fasteners will allow for the expansion and contraction of the standing seam metal roof.
Once the first panel is in place, the adjacent panel gets installed right next to the preceding panel forming a connecting point at the seam. The seam acts as a locking mechanism along side the panel. There are types of locking mechanisms for standing seam; snap on, which as the name suggests, gets put over and snapped on top of the preceding panel. The second type is the field formed seam, which requires special bending tool to securely lock the seam. The snap system takes less time to install than the field locked version. This something to keep in mind when ordering your system from the supplier.

Anti Lock Braking System
Anti lock braking system, abbreviated as ABS, is an advanced car security system fitted in many of the modern Indian cars to prevent skidding. The term is derived from the German term ‘antiblockiersystem’.
The main objective of anti-lock braking system is to enhance stability and stopping capability of the car. While driving on slopes or slippery surfaces, the car has a tendency of skidding. In such cases, the innovative anti lock brakes help in locking the wheels and prevent skidding. Locked wheels on concrete cement sometimes create flat spots but in case of anti lock brakes, these spots are prevented.
Components
An ABS system mainly comprise of electronic control unit, four wheel sensors, hydraulic valves and vehicle brakes. The electronic control unit helps in monitoring and regulating the rotational speed of each wheel. Four wheel sensors help in scanning the speed of each wheel and if the control unit reads low speed then other wheels are locked automatically. Hydraulic valves help in reducing the pressure on each wheel, effectively lowering down the braking force on individual wheels. Vehicle brakes further help in building pressure back up through the hydraulic motor.
Raw Materials
Most of the new cars found on Indian roads are equipped with anti lock brakes composed of soft iron, mainly cast. Iron is used because it has high magnetic permeability and low magnetic reluctance. These properties help in passing magnetization to each tooth of the brake and cause momentary concentration. The electronic controller is composed of cast aluminium housing and the hydraulic brakes are made using copper coil elements with steel valves and bodies. They are housed in the same casing composed of cast aluminum. All the electrical wiring in the system is composed of copper usually with cross-linked polyethylene insulation. Connectors are made using plastic with internal copper contacts.
Types
There are mainly three types of anti-lock brakes: four channel four sensors ABS, three channel three sensors ABS and one channel one sensor ABS. Four channel four sensors ABS is a system with speed sensors fitted on all four wheels with a separate valve. This helps in monitoring rotation speed of each wheel and ensures that each wheel achieves maximum braking force. Three channel three sensors ABS is a system with speed sensors and valves fitted on each of the front wheels and one common sensors and valve for both the rear wheels. This helps in monitoring the speed of individual front wheels for maximum braking force and combined monitoring of rear wheels which reduces the braking force. One channel one sensor is a system with one sensor and one valve for monitoring all four wheels. This system is mainly used in trucks.

HELP! need to fix my refrigerator from leaking. I was drilling it.?
I was trying to put a latch/lock on my fridge and I must have drilled a copper pipe and now my fridge seems to be leaking a gas, probably coolant. How do I stop it from not leaking? I'm gonna guy try put some sodder in it to cover it up since it's metal, but is there any other way to fix it? I don't have a lot time right now since it's leaking right now!
The refrigerant is pumped under pressure and simply soldering will not work. The unit will have to expel all the refrigerant, be soldered with silver solder, have a vacuum pulled on the inside of lines, then recharged. May be better to buy a new one.
