1. A flexible, resilient, gland to seal an annular opening in an electrical wall box, the gland comprising:
an annular first portion having a central bore formed therethrough, the annular first portion including:
a first open end;
a second open end;
a continuous membrane disposed transversely across an internal diameter of the annular first portion proximate the second open end, wherein the membrane includes:
a first portion having first thickness; and
a second portion having second thickness that is less than the first thickness, the second portion to permit the passage of an electrical conductor therethrough, the second portion of the membrane proximate a center point of the central bore of the annular first portion;
an annular second portion having a central bore formed therethrough, wherein a diameter of the second portion of the membrane corresponds to an inside diameter of the central bore of the annular second portion; and
an annular Intermediate portion with a central bore formed therethrough, the annular intermediate portion fluidly coupling the first open end of the annular first portion with the annular second portion.
