Product Overview
The Heyco M3234GBR-SM is a 5-hole Heyco-Tite liquid-tight cordgrip (SMCG 3/4) for PV cable. Heyco's solar liquid-tight cordgrip datasheet and product page list five holes for 4.4–5.5 mm conductors, a skinned-over break-thru gland, assembled metal locknuts included, and an IP 68 rating.
Skinned-over holes let you use from one to five of the available openings while unused holes stay liquid-tight.
Best For
- Multiple PV conductors into an enclosure: Junction boxes or combiner entries sized for 3/4" NPT.
- Jobs that specify M3234GBR-SM: When the PV cable OD falls in the 4.4–5.5 mm gland range.

What You May Also Need
Usually required
- PV cable whose outer diameter fits the 4.4–5.5 mm gland range.
- Enclosure opening for 3/4" NPT / 1.109 in clearance.
May be required
- M3234GDA-SM: Use instead when the cable is Enphase Q Cable, not round PV wire.
Optional upgrades
- Heyco female threaded couplings and Heyco-Flex III tubing: Heyco recommends these with its multi-hole cordgrips to insulate exposed PV wiring into combiner or inverter enclosures (Heyco solar cordgrip datasheet).
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Match cable outer diameter to the 4.4–5.5 mm gland range before ordering.
- Not for Enphase Q Cable oval profiles — use M3234GDA-SM.
