About the Marvoloc Product

Tremar has created a revolutionary product called Marvoloc, which is proudly made and manufactured right here in the USA. It is UL and CUL listed, passing all necessary NEC codes. Marvoloc is one of the most efficient ways to achieve device adaptation for any devices to a 4-inch square box and a 4-11/16 box with the help of our Marvoloc adapters. Additionally, we offer an excellent solution for round devices ranging from 15-60 amps, which can be accomplished using just two plates. Invented in the early 2000s by Marvin Pinkowski, Marvoloc is now managed by his grandson Trevor Pinkowski.
