Milbank M5-144 – Frequently Asked Questions

1) What exactly is a Milbank M5-144 meter isolation disc sleeve used for?
The Milbank M5-144 is a Mylar disc sleeve used as a metering accessory to electrically isolate a meter, so it insulates rather than mounts or supports anything. Each sleeve is 0.005 inch thick with 3 x 4 inch face dimensions, thin enough to sit between components without changing how the meter seats.
2) How many disc sleeves come in a Milbank M5-144 pack?
One gross, so 144 sleeves per pack. That matches the M5-144 model number and makes it a bulk buy rather than a single-unit item, which is what an electrical contractor or utility crew doing repeat meter work usually wants.
3) What are the dimensions of the Milbank Mylar meter isolation sleeve?
Stated size is 0.005 x 3 x 4 inches: 0.005 inch material thickness, 3 inch width, 4 inch height. That 5-thousandths thickness is why it can be inserted without shimming the meter out of its socket.
4) Does the Milbank M5-144 sleeve come with knockouts or mounting holes?
No. The M5-144 is a plain Mylar sleeve with no knockouts. If you need a part with knockout provisions for conduit or wiring, this is not it, this is strictly a flat insulating sleeve.
5) What part number and UNSPSC code should I put on a purchase order for Milbank meter isolation sleeves?
Order Milbank M5-144 for the one-gross pack of 0.005 x 3 x 4 inch Mylar disc sleeves. The UNSPSC classification is 39121321, which is what most institutional and government procurement systems will want on the line item.
6) Why Mylar for a meter isolation sleeve instead of a fiber or plastic shim?
Mylar is specified here as the insulation material because it holds dimensional stability at only 0.005 inch thick while still giving dielectric separation. A thicker fiber shim would change the seating depth; Mylar at 5 mils does not.
7) Is the Milbank disc sleeve coated or painted?
Unpainted. The Mylar is supplied bare, with no coating applied, so nothing on the surface to scratch off or contaminate the meter contacts.
