Blue Sea Systems SMS Enclosure Gland, PG7, for #14 to #10 Wire

Overview

The Blue Sea Systems 3124 is a small PG7 cable gland for one #14 to #10 wire in the SMS Surface Mount System. It fits cable outside diameters from 0.114 to 0.250 in. (2.9 to 6.4 mm) and uses a 0.492 in. (12.5 mm) clearance hole, so it is sized for small single-wire entries rather than larger jacketed cable runs.

This gland is used when a single conductor needs to pass through the wall of an SMS enclosure without leaving a loose opening around the wire. In marine electrical work that matters when the enclosure is mounted in places such as a machine space, lazarette, or shore cord storage compartment, where the cable entry needs to stay controlled and properly sealed. It is used with Blue Sea Systems SMS enclosure applications including part numbers 3116 and 3119.

Key features

• PG7 gland sized for one #14 to #10 wire.
• Accepts cable outside diameters from 0.114 to 0.250 in. (2.9 to 6.4 mm).
• Requires a 0.492 in. (12.5 mm) clearance hole for nonthreaded mounting.
• Compact body with 1.17 in. (29.7 mm) max overall length for enclosure installations with limited wall depth.
• 0.59 in. (15.0 mm) wrenching flats for tightening during installation.
• Used with Blue Sea Systems SMS enclosure setups, including 3116 and 3119.

Compatibility and fit

Fit depends on cable outside diameter as much as conductor gauge. A wire may fall in the #14 to #10 range and still be too large or too small at the jacket for this gland, so the cable OD window of 0.114 to 0.250 in. is the measurement that matters most when confirming the seal. This version is for a single wire pass-through, not a bundled cable entry.

Installation and setup

For SMS enclosure work, the gland is installed after drilling the correct clearance hole and tightening the sealing nut around the wire entry. Keeping gland entries on the bottom side of the enclosure is the usual approach on SMS installations because it helps preserve the enclosure seal as the cable run drops into the box.

Use on board

This part makes sense for refits, service work, and panel changes where an SMS enclosure needs one more single-conductor entry without opening a larger cable hole than necessary. It is a good fit for boat owners and installers working on Blue Sea SMS enclosures in utility spaces where clean wire routing and a sealed pass-through matter.
