Combination Screw Coupling (for use with a standard plica and a steel electrical conduit without screws)
Caution
Product Description
[Features]
• Combination coupling for connecting a plica tube and steel electrical conduit without screws.
• The plica tube connection is a screw connection, and the steel electrical conduit connection is fixed in place with small screws.
• The tensile strength of the plica tube and couplings is 500 N (JIS medium).
• The tensile strength of the coupling with the electrical conduit is 500 N for model numbers 10–30 (JIS medium), and 1, 000 N for model numbers 38 and above (JIS heavy).

The connection to a plica tube is a screw-in type, and the connection to a steel conduit is a torque machine screw mount type.
Tensile strength of the plica tube and coupling is 500 N (JIS C8461-22 code 3 medium).
The tensile strength of conduit and coupling is 500 N for #10 to 30 (JIS C 8461-22, classification code is 3: medium), and 1,000 N for #38 and above (JIS C 8461-22, classification code is 4: heavy).
Please use a steel conduit without tapping.
