Heyco®-Tite Solar Masthead Cordgrips – Skinned-Over Break-Thru (IP68 Rated)

Part Numbers: M3200GAH (MID-MNSR-1000) | M3231GCZ | M3234GBS-SM | M8437GBT-SM
CSA & UL Certified • Liquid-Tight • Built for Solar Installations

The Heyco®-Tite Skinned-Over Break-Thru Solar Masthead Cordgrip provides IP68-rated strain relief and sealing for photovoltaic wiring in combiner boxes, inverter housings, and junction enclosures.
Each gland offers long-term protection against moisture, dust, and mechanical stress, keeping your system compliant and reliable under harsh Canadian weather conditions.

Made from UV-stabilized Nylon 6/6 with a TPE sealing gland, Heyco cordgrips are trusted across the solar industry for their flexibility, chemical resistance, and easy installation. The skinned-over break-thru design allows unused holes to remain sealed while maintaining a watertight fit for active conductors.

Key Features

  • IP68-rated protection: Fully dust- and water-tight for outdoor, rooftop, and industrial solar environments.

  • Multiple configuration options:

    • M3200GAH (alias MID-MNSR-1000): 2-hole gland supporting two 6 mm PV conductors — a direct replacement for the MidNite MNSR-1000 strain relief.

    • M3231GCZ: 1-hole gland for a single PV cable or sensor lead.

    • M3234GBS-SM: 3-hole gland for mixed conductor sizes (two standard + one larger).

    • M8437GBT-SM: 5-hole gland for multiple PV string circuits or combined cable bundles.

  • Dual-diameter flexibility: Each model accommodates different conductor sizes in one fitting.

  • Integral sealing ring: Ensures consistent compression and a reliable leak-free seal.

  • Rugged construction: Nylon 6/6 body with TPE gland resists UV, salt, oil, and common solvents.

  • Certified for North America: UL E51579 / CSA 93876 compliant.

  • Temperature range: Static –40 °C to +112 °C | Dynamic –20 °C to +100 °C.

  • Metal locknut included for quick, secure installation.
