Large South Africa or Small South Africa Hollow Copper Foot South Africa Plug (Type M Plug), in compliance with South African standard SANS 164, features a stamped hollow structure (often reinforced with plastic) with pins that are more environmentally friendly and cost-effective compared to solid copper feet. However, it has slightly weaker strength and is widely used as a 220V/16A power plug in South Africa and some African and Asian countries.

Hollow feet vs. solid feet: The inner cavity of hollow feet is often reinforced by injection molding, with slightly lower conductivity but more environmentally friendly and easy to process; Solid feet are machined with whole copper, which provides better mechanical strength and conductivity, but comes at a high cost and carries a high risk of lead content.

Attention: Hollow pins do not mean inferior quality. As long as they comply with SANS 164 and IEC 60884, and are certified (such as SABS), they can be used safely; But inferior imitations may use thin-walled hollow feet and recycled plastic, which poses a risk of overheating. ‌‌
