Usually “Flanged Coupler” is used for “Adaptable Box”, and “Solid Coupler”, “Locknuts Hexagon”, “Milled Edge Lock Rings”, “Male Brass” and other accessories are usually used in “Switch & Socket Box“.
As the terminal of the circuit system on the wall and floor, not only the doorbell, light switch and power switch matching the “Switch & Socket Box”, also the lamp fittings installed on the roof matching the “Conduit Box”.
we introduce the back and outlet box.This side is the same as normal box,but the back we can see there is an additional way for extending conduit pipe.Usually we use it around the corner.
All above boxes not only supply regular 20-25mm,also can supply bigger size,such as 32mm.
We usually use the accessory called Nipple,the difference between the nipples and couplers is the thread.Solid coupler is inside but nipple is outside.Their function is the same to connect pipes.
The usage and shape of the extension box is similar to that of regular box.The difference is the installation scenario.
This is installed in the case of two floors of suspended ceiling or wooden support,the back needs to be fixed with screw fittings.Also can used to connect with Flexible conduit that the same as terminal box.

For example，”Dome Cover”, “Hook Plate” , “Ball & Socket Cover”, “Male Hook” can be installed all types of lamps perfectly.You can choose right one for the installation according to various height.
For terminal box,we have another box called loop in 1-4 hole box.They also usually use in the roof.For example,it connect flexible conduit with brass accessories.The difference is loop in box connect the tube from the top,terminal box from the side.
When the straight length of the tube beyond 15 meters, or the wire tube has 3 turns and the length beyond 8m, the junction box must be installed in halfway,now we can use through or angle box. Because it’s easy to check the wiring.
Tee box and Intersection box are also play role of connection.As the name implies,Tee box can connect 3 ways of pipes and Intersection can connect 4 ways.
As you know the normally length of the conduit tube is 3.75 meters/pc. Then we will use the “Solid Coupler” to connect the pipes to meet the length that you required.
When pipes turning we need to use bends, tees and other accessories.We have two styles of bend. One is a simple, the other with a cover, which can be opened for wire inspection.
