Panduit BT4LH-TL0 Dome-Top Barb Cable Tie, 14.9in, 250-Pack

Overview

The Panduit BT4LH-TL0 is a 14.9-inch Dome-Top™ barb cable tie built for demanding wire-management applications where standard ties fail — indoors and outdoors alike. The patented barbed locking design with a stainless steel locking tang delivers 120 lb tensile strength across the full range of bundle diameters, which means you get consistent, repeatable hold whether you're securing a thin single-cable run or a large conduit harness. Smooth, rounded edges on the Dome-Top™ head prevent insulation abrasion, a detail that matters in panel builds and rack wiring where ties frequently contact adjacent cable jackets.

Fabricated from UV-stabilized Nylon 6.6, the BT4LH-TL0 holds up in direct sunlight and wet outdoor environments without the embrittlement and snap-failure common in untreated nylon ties. Each pack ships 250 ties; the master carton holds 2,500 — practical for project-scale installations where per-tie cost and reorder frequency matter.

Key Features

• Patented Dome-Top™ Barb Design: The barbed locking mechanism engages continuously across the full harness diameter, not just at discrete ratchet points. This means you're not locked into fixed bundle sizes — infinite adjustment gives a clean, low-profile termination at any harness OD without leaving a loose tail sticking up.
• 120 lb Tensile Strength: At 120 lb, this is a heavy-duty tie in a semi-lightweight cross-section profile. Suitable for large wiring harnesses in telecom cabinets, electrical panels, and industrial cable trays where standard light-duty ties would creep or fail under vibration.
• 14.9-Inch (378 mm) Overall Length: The longer format accommodates large-diameter bundle groups — think multi-conduit runs, bundled power and data at junction boxes, or large-diameter harnesses in automation enclosures. At 14.9 in., you have enough working length to cinch a substantial bundle and still insert through tight panel real estate.
• UV-Resistant Nylon 6.6 (Black): UV degradation is the most common failure mode for outdoor cable ties. The BT4LH-TL0 uses UV-stabilized Nylon 6.6 rated for outdoor exposure — no chalking, no brittleness from sun exposure. Black coloring also provides additional UV protection beyond the stabilizer additive itself.
• Stainless Steel Locking Tang: Where all-nylon self-locking ties can slip under sustained load or temperature cycling, the metal tang maintains grip. This is the correct pick for applications with thermal cycling, mechanical vibration, or code requirements for positive retention.
• Multi-Standard Certifications: The BT4LH-TL0 meets UL 62275 (file E56854), CSA-C22.2 No. 62275 (file 31212), QPL-AS23190 (military spec qualification), BV file ACE 14/601/01, and RoHS directive compliance. UL/CSA listing directly supports use in NEC/CEC-compliant installations; QPL-AS23190 qualification opens the door for defense and aerospace harness applications without a separate approval process.
• 250-Unit Pack / 2,500-Unit Carton: The 250-pack quantity is sized for project-level use — enough to complete a mid-scale installation without over-buying. For large-scale deployments, the 2,500-unit master carton (10 packs) cuts per-unit cost and eliminates mid-project reorders.

Integration & Compatibility

Panduit specifies the BT4LH-TL0 for use with the following Panduit cable tie installation tools: GTH-E, GS4H-E, GS4EH-E, PTH, STH2, and ST3EH. Using a compatible tensioning tool ensures consistent tension and clean tail cut-off — hand-installation at this tensile rating risks inconsistent cinch force and leaves sharp tail remnants. If you're already running a Panduit tool gun on the job, verify your model against this list before ordering at scale.

Cross-reference: the BT4LH-TL0 is a direct equivalent or replacement for competitor parts 08437, 10039, CTSB15BK120-D, IMET4LH-D0, TBCOTY27MX, and TY27MX — useful when standardizing vendor inventory or substituting on an existing job spec.

Frequently Asked Questions

Q: Can the BT4LH-TL0 be used outdoors in direct sunlight?

A: Yes. The BT4LH-TL0 is manufactured from UV-stabilized Nylon 6.6 and is rated for outdoor use including direct UV exposure. The black color adds a secondary layer of UV protection beyond the stabilizer additive, making it appropriate for exterior conduit runs, rooftop cable management, and outdoor panel installations.

Q: What installation tools are compatible with the BT4LH-TL0?

A: Panduit specifies these tools as compatible: GTH-E, GS4H-E, GS4EH-E, PTH, STH2, and ST3EH. Using a matched tensioning tool ensures repeatable tension and a clean tail cut. Hand-tightening is possible but not recommended at 120 lb target tension for consistent results across a large harness job.

Q: Does the BT4LH-TL0 meet UL and CSA electrical standards?

A: Yes. The BT4LH-TL0 carries UL 62275 listing under file E56854 and CSA-C22.2 No. 62275 listing under file 31212. Both certifications are directly relevant to cable management in NEC and CEC compliant electrical installations. It also meets QPL-AS23190 for military/aerospace harness qualification and is RoHS-compliant.

Q: What bundle diameters does the 14.9-inch BT4LH-TL0 accommodate?

A: The barbed Dome-Top™ design offers infinite adjustment across the full harness diameter range the 14.9-inch (378 mm) length supports — there are no discrete ratchet steps. The practical maximum bundle diameter depends on the usable tail length after the head seats; refer to Panduit's harness range specification for the exact min/max OD values.

Q: How many ties are in each package, and is a larger carton quantity available?

A: Each retail package contains 250 ties (BT4LH-TL0). The master carton quantity is 2,500 (10 packs). The carton option is the practical choice for large-scale panel shops, integration firms, or contractors running multi-rack deployments where per-unit economics and reducing reorders are a factor.

Q: Is the BT4LH-TL0 RoHS compliant?

A: Yes. The BT4LH-TL0 is listed as compliant with the RoHS directive, making it suitable for projects and facilities with restrictions on hazardous substances in electrical and electronic equipment.

The detail I keep coming back to on the BT4LH-TL0 is the stainless steel locking tang — at 120 lb tensile strength with a 14.9-inch working length, that metal retention point is what separates this tie from the all-nylon alternatives when you're working in environments with thermal cycling or vibration. I've seen all-nylon ties at this tension rating slowly back off over time in hot telecom rooms; the metal tang doesn't creep.

Technical Highlights:

• QPL-AS23190 Qualification: This military-spec qualification listing means the BT4LH-TL0 can be specified directly on defense and aerospace harness drawings without a separate approval process — saves significant procurement and engineering time on those jobs.
• Infinite Adjustment (Barb Design): No ratchet teeth means the tie seats cleanly at any bundle OD within the 14.9-inch working length. On production harness lines where bundle diameters vary by even a few millimeters, this eliminates the gap-plus-slop problem you get with standard step-lock ties.
• UV-Stabilized Nylon 6.6 — Black: The combination of UV stabilizer additive and black pigment means outdoor installations don't need re-tying after the first hot summer. Standard natural-color nylon at this length can become brittle and snap under load within 18–24 months of direct sun exposure in southern climates.

Deployment Considerations:

• Match your tool to the approved list (GTH-E, GS4H-E, GS4EH-E, PTH, STH2, ST3EH) before starting production. At 120 lb target tension, off-spec tools will either under-tension — leaving sloppy bundles — or over-tension and nick the tie, creating a stress-riser failure point that won't show up until the harness is in service.
• At 14.9 inches, this tie is long for tight enclosures — verify you have clearance to seat the tensioning tool head before ordering at scale. For compact panel interiors with 10–12 inch bundle runs, a shorter tie in the same BT family will be easier to work with and won't leave excess tail to manage.

The BT4LH-TL0 is the correct specification for outdoor security camera runs, large-format telecom harness production, and any installation where QPL-AS23190 compliance or UL 62275 listing is a contract requirement — not a general-purpose tie for small enclosures.
