What this conduit protects

The SDC PT-3V is an 18" (447mm) stainless steel armored flex conduit with an aluminum termination box. It shields low-voltage wiring inside hollow metal and aluminum frames. Installers use it to route cables securely through door openings.

How the termination box changes installation

The integrated aluminum termination box provides a fixed mounting point at the frame. This allows cables to enter the conduit cleanly without exposed transitions. It simplifies routing through hollow profiles and reduces the chance of wire damage at the entry.

Where the 18-inch length fits and where it does not

The fixed 18-inch length suits standard door-frame transfers but cannot span taller openings or longer cable runs. It is not designed for surface-mounted raceway or outdoor exposure. Builders needing extended reach or different mounting styles must select another solution.

Questions about this item

Will the aluminum termination box need replacement before the stainless steel conduit?

The armored flex conduit is made of stainless steel and the termination box is aluminum; both are new and designed for hollow metal or aluminum frames.

What is the maximum run length before signal loss in this conduit?

The PT-3V measures 18 inches or 447 mm end to end, which is the installed length for a single door transfer.

Does the conduit get hot or add resistance when power runs through it all day?

The stainless steel armored flex conduit serves as a protective raceway and does not carry current itself, so it produces no heat or noise.
