Dimensions:2 3⁄4" H × 2 3⁄4" W
Primary Embossing:The Primary Embossing is typically found on the front of the insulator and usually identifies either the manufacturer (such as "Hemingray") or the company that the insulator was made for (such as "AM.TEL.&TEL.CO.")

Insulators with No Name or No Embossing are denoted as such.

Insulator Overview

This rare threaded spool style was manufactured by Hemingray (a specimen was unearthed at the Hemingray dump in May 2008 with an unplugged hole). These were found used in at least two different applications: In 2020, two of these were found as the middle insulator on a custom 3 insulator bracket. Another specimen has been found with a hook attachment. It is unknown what "B.E.L.Co." stands for, but some have speculated "Belmont Electric Light Company", as these were found in service in the Belmont district of Philadelphia, PA. More of these have surfaced over the past 10 years, but still only a handful are known to the hobby.

Known Embossing
Primary EmbossingThe Primary Embossing is typically found on the front of the insulator and usually identifies either the manufacturer (such as "Hemingray") or the company that the insulator was made for (such as "AM.TEL.&TEL.CO.")

Insulators with No Name or No Embossing are denoted as such.
EINThe Embossing Index Number (EIN) is a unique number assigned by the collecting hobby to each distinct embossing for an insulator design. It is normally shown in brackets, e.g. [050].
EmbossingMost common terms:
(F-Skirt): Front Skirt
(R-Skirt): Rear Skirt
/: New line of embossing
{}: Special note (not embossed on the insulator)
[#]: Represents a number

Other terms:
{MLOB}: Mold Line Over Base
(F-Crown): Front Crown
(R-Crown): Rear Crown
(F-Umbrella): Front Umbrella
(R-Umbrella): Rear Umbrella
BaseThe base is the bottom of the insulator. Hemingray made 4 different types of bases:

1. SDP: Sharp Drip Points
2. RDP: Round Drip Points
3. CB: Corrugated Base
4. SB: Smooth Base
Year AddedThis is the year that this embossing was officially recognized and added to the McDougald (1991-2008) or Briel (2011-2023) insulator price guides. It is not necessarily the year this embossing was discovered.

Removed Embossing

The following embossing(s) were removed from the price guide because they could not be verified to exist, were consolidated with other embossings, or were otherwise ambiguous/inaccurate. They are preserved here for historical purposes.
