Panduit TMEH3S13-D350 Medium Torque Heavy Duty Cable Tie Mount

Overview

The Panduit TMEH3S13-D350 is a medium torque heavy duty tie mount engineered for organized, permanent cable management in demanding industrial and commercial environments. Constructed from impact-modified, heat-stabilized, weather-resistant Nylon 6.6 in black, this stud-mount or bolt-on hardware anchors cable tie bundles securely through a 1/2" (13mm) mounting hole — the kind of repeatable, no-rework installation that matters when you're working across large cable trays, harness routing paths, or structured cabling runs at scale. Sold in a pack of 500, the TMEH3S13-D350 is sized for project-level consumption rather than spot repairs.

Whether you're routing security camera homerun cables along a steel stud grid, organizing low-voltage bundles in a data closet, or managing wire harnesses on panel assemblies, having the right quantity of a reliable mount on hand prevents the shortcuts that create problems at inspection. Browse the full Panduit cable management line for complementary hardware that pairs with these mounts across structured cabling and wire-routing applications.

Key Features

• Impact-Modified Nylon 6.6 Construction: The base polymer is heat-stabilized and weather-resistant — not standard nylon that softens under continuous thermal load. In ceiling plenums or outdoor-adjacent enclosures where temperatures cycle, this matters more than it sounds. You won't find mounts that have relaxed and let bundles sag a year after installation.
• 1/2" (13mm) Mounting Hole Compatibility: Designed for standard 1/2" stud or bolt patterns common on electrical enclosures, strut channel, and steel framing members. No drilling, no adapters — the mount drops onto the stud and the retention tab locks it down. That's the correct fit for the overwhelming majority of commercial panel and rack infrastructure.
• Retention Tab: The built-in retention tab keeps the mount positively secured to the stud during installation before the tie is applied. This prevents the mount from spinning or backing off when you're working one-handed or overhead — a genuine time saver on high-density cable runs where you're placing dozens per session.
• Universal Tie Cross-Section Compatibility: Accepts Panduit ties in miniature, intermediate, standard, heavy, and extra-heavy cross sections. That flexibility means one SKU of mount covers the full range of bundle diameters you'll encounter on a mixed low-voltage and power-adjacent installation — you're not stocking five different mount variants.
• RoHS Compliant: Meets Restriction of Hazardous Substances requirements, which matters for projects with environmental compliance mandates — government facilities, healthcare installations, and any build-out subject to EU or equivalent domestic RoHS standards. Verification at the SKU level, not just the brand.
• 500-Unit Pack Quantity: At 500 pieces per pack, the TMEH3S13-D350 is priced and packaged for contractors and integrators running full-building or multi-zone cable management work, not for one-off repairs. Per-unit cost drops significantly versus small-quantity purchases, and having inventory on-site means installers aren't waiting on a reorder mid-job.
• Black Colorway: Matches standard black cable ties and blends with dark-finished cable trays and raceways. Not a cosmetic footnote — on visible cable runs in finished spaces or data centers, color consistency is part of a professional install.

Integration & Compatibility

The TMEH3S13-D350 is designed for use alongside cable tie and mount systems across the Panduit product family, and integrates directly with any installation using 1/2" (13mm) mounting studs or bolts. It pairs naturally with Panduit miniature through extra-heavy cross-section ties, making it a single-SKU solution for multi-gauge wire bundles in the same run. For installations requiring complementary structured cable management hardware — raceway, duct, or tray systems — the TMEH3S13-D350 fits into a broader organized cabling plan without requiring adapter hardware or special tooling. For applications where cable tie mounts will be used alongside power distribution and panel infrastructure, the 1/2" hole sizing aligns with common stud patterns found on DIN rail enclosures and electrical panels. Consult a cable tie mount selection guide to match tie cross-section to bundle diameter before ordering tie inventory.

Frequently Asked Questions

Q: What mounting hole size does the TMEH3S13-D350 require?

A: The TMEH3S13-D350 requires a 1/2" (13mm) mounting hole. It is designed for bolt-on or stud-mount installation using this standard hole size, which is common across electrical enclosures, strut channel, and steel framing.

Q: Which cable tie cross-sections are compatible with the TMEH3S13-D350?

A: The TMEH3S13-D350 is compatible with Panduit cable ties in miniature, intermediate, standard, heavy, and extra-heavy cross sections — covering the full range of bundle diameters typically encountered on commercial and industrial installations.

Q: Is the TMEH3S13-D350 RoHS compliant?

A: Yes. The TMEH3S13-D350 meets RoHS (Restriction of Hazardous Substances) compliance standards, making it suitable for projects with environmental or regulatory requirements including government, healthcare, and EU-regulated facilities.

Q: What material is the TMEH3S13-D350 made from?

A: The mount is constructed from impact-modified, heat-stabilized, weather-resistant Nylon 6.6 in black. This formulation offers greater thermal and mechanical durability compared to standard nylon, suitable for environments with temperature cycling or exposure to the elements.

Q: How many units are included in a pack of TMEH3S13-D350?

A: Each purchase includes 500 units of the TMEH3S13-D350, packaged for project-level or contractor-scale deployments.

Q: What are the overall dimensions of the TMEH3S13-D350?

A: The TMEH3S13-D350 measures 1.15" (29.3mm) wide, 1.85" long overall, and 0.77" (19.6mm) in height.

Ted Perry

When I spec cable tie mounts for a structured cabling or low-voltage installation, the material formulation is what separates a mount that holds for a decade from one that becomes brittle and fails mid-lease. The TMEH3S13-D350 uses impact-modified, heat-stabilized Nylon 6.6 — not commodity nylon — which gives it measurably better performance in thermal cycling environments like above-ceiling cable runs, mechanical rooms, or outdoor-adjacent enclosures. That's the spec I look at first on this product.

Technical Highlights:

• 1/2" (13mm) Stud Fit: Aligns with the dominant hole size on electrical strut, panel studs, and steel framing members — no adapter required. Saves per-point installation time on large-scale runs.
• Universal Tie Acceptance: Compatible with miniature through extra-heavy Panduit tie cross-sections, so one mount SKU covers every bundle gauge on the job. Reduces inventory SKU count for contractors managing multi-zone installs.
• 500-Unit Pack Quantity: At 500 pieces, the TMEH3S13-D350 (often searched as TMEH3S13 D350) is packaged for full-building deployments. Per-unit economics are meaningfully better than small-quantity orders, which matters on jobs where mount count runs into the thousands.

Deployment Considerations:

• Confirm stud or bolt diameter is true 1/2" before ordering at scale — some metric panels use M12 studs (nominally 12mm) which are close but not identical; the fit difference can cause retention tab issues under vibration.
• The retention tab secures the mount to the stud prior to tie installation, but is not designed as the primary load-bearing element — final bundle weight should be carried by the cable tie, not the mount body alone.

The TMEH3S13-D350 is the right call for commercial integrators running large low-voltage and security camera cabling projects on steel-stud construction where a 1/2" bolt pattern is standard — particularly when the job spec calls for RoHS-compliant hardware throughout.
