Minerallac ISER40 – Frequently Asked Questions

1) Can Minerallac ISER40 staples be used outdoors on an exterior service entrance run?
Yes. The molded plastic insulation on the ISER40 is UV stabilized for severe weather conditions, so it holds up on an exposed exterior wall run from the meter base up to the weatherhead.
2) Will a standard romex cable staple work for 4/0 SER instead?
No. A common NM cable staple is sized for a flat 12/2 or 14/2 jacket and will not close over 4/0 SER. The ISER40 has a 1.438 inch diameter saddle built specifically for #4/0 Type SE, Style SER, so the cable seats without crushing the jacket.
3) Is the ISER40 staple insulated so it won't cut the SER cable jacket?
The saddle is plastic injection molded over the staple, so the only thing contacting the cable jacket is molded plastic, not bare metal. The legs themselves are high-carbon steel for drive strength into wood framing or sheathing.
4) How many Minerallac ISER40 staples come in a pack?
ISER40 insulated service entrance staples are packed 100 to a box, which is enough to strap several complete service runs on a multi-family or tract job.
5) What color are the Minerallac ISER40 staples, and will they blend with gray SER cable?
Silver grey. That matches typical gray SER jacket closely enough that the straps disappear on a wall run, which matters when the service is on a street-facing elevation.
