The y-clevis clevis is a short, fixed adapter link with two different terminations: one end is a Y-clevis — a forked jaw shaped to capture a ball or tongue fitting — and the other is a conventional clevis that pins to the next component in the string. Unlike the hot line link, it has no stick-operable disconnect function; once assembled, it stays in the string as a permanent geometry converter. Its job is simple but essential: letting utilities combine hardware from different eras and suppliers in one insulator string without welding, bending, or stacking multiple links.
Strings accumulate mixed hardware over decades of maintenance. A structure may carry a ball-ended polymer insulator installed last year, a tongue fitting from the original 1980s build, and a yoke plate added for a reconductoring project. The y-clevis clevis ties those conventions together with a single pinned joint on each side, keeping the load path straight and the assembly short. As a casting foundry, we focus on the details that keep that joint reliable for decades: fully machined bores, generous fillets where the jaw meets the shank, and a galvanized coating thick enough to survive pin-tightening torque during installation.

Installation is a two-pin operation. Seat the Y-clevis jaw over the ball or tongue, verify the captured fit, insert the cotter key, then pin the clevis end to the mating hardware and spread the cotter. Crew-level guidance from field feedback:
Confirm that both cotter keys are fully spread before leaving the structure — an unspread pin is the leading cause of link loss in service.
Keep the load path in line; avoid using the y-clevis clevis as a swivel or allowing side loading the jaw was not designed for.
Match strength classes: the adapter should equal or exceed the rating of the weakest fitting in the string.
Typical placements include adapter positions between ball-eye hardware and clevis-based yoke plates, junction points in drop leads, and conversions inside dead-end assemblies where older tongue fittings meet newer string components.
We manufacture the y-clevis clevis to drawing or sample. Frequently requested modifications include wider Y-jaws for oversized tongues, doubled clevis ends (y-clevis–y-clevis) for special transitions, elongated pin spacing for crossarm hardware, and stainless cotter kits. Sample lead time is typically 2–3 weeks from drawing approval, with first-article dimensional reports included for utility sign-off.
Every production lot is checked for: bore diameter and jaw width with go/no-go gauges; jaw alignment and cotter-hole condition; hot-dip galvanizing thickness by magnetic gauge against ASTM A153; and tensile sampling on a calibrated pull tester to confirm the rated class. Surface defects are screened visually before galvanizing; castings with subsurface porosity in the load path are rejected. Parts ship 50–100 per carton on export pallets with lot traceability.
Q: Is a y-clevis clevis the same as a hot line link?
A: No. Both connect a Y-clevis end to a clevis end, but the hot line link is designed to be opened with a hot stick for live-line disconnect; the y-clevis clevis is a permanent fixed adapter.
Q: What ball or tongue sizes does the Y-clevis end capture?
A: Standard string hardware sizes per your drawing — send us the mating fitting and we will confirm jaw geometry.
Q: Can it be supplied in a clevis–clevis version?
A: Yes, we produce clevis-eye and y-clevis–y-clevis variants to drawing.
