Western has the largest installed base in North America, which makes its edges the most copied and the most often bought wrong. The brand does not identify the edge: the mounting pattern on your blade does, and Western has changed that pattern across model generations.
We drill Western-pattern edges in carbide, steel and poly, and we confirm the hole pattern against a drawing or a photograph before production rather than by model year alone.
- MountMeasured at the blade, not taken from the UltraMount kit number
- EdgesCarbide, steel and poly, drilled to your pattern
- ThicknessMatched to the blade, with bolt length quoted alongside
- HardwareRecessed bolt holes so heads sit below the wear plane
- CoverageStraight blades and V-plows; send the mount details
- TraceabilityBatch reference on every carton, back to the sintering run
Why Western edges get bought wrong
Three reasons, and none of them are about material.
- The pattern moved. An edge that fits a 2015 blade does not automatically fit a 2020 one, even where the blade width is the same.
- UltraMount is the truck interface, not the blade interface. The mounting system tells you how the plow attaches to the vehicle; it says nothing about the bolt spacing on the edge.
- Aftermarket edges vary in countersink. A pattern drilled for plain hex heads will not seat flush where the original used countersunk hardware.



Measure the blade, then choose the material
| Your route | What we recommend | Reason |
|---|---|---|
| Abrasive pavement, long hours | Carbide edge | Wear life where impact risk is low |
| Pavers and decorative surfaces | Poly or rubber-flex | Protects the surface the blade works on |
| Gravel and shoulders | Steel edge | Impact tolerance beats hardness on loose stone |
| Mixed routes | Steel first, trial carbide | One season of field data settles the grade |
Pattern check
Send the blade width, edge height, thickness and centre-to-centre hole spacing across three holes, with a photo of the mount. If the plow has been re-drilled after a repair, only the photo will catch it.
Fitment
Edges are produced to your blade rather than to a catalogue entry. Send a drawing, a part number or a photograph of the mounting with measurements, and we confirm bolt spacing, hole diameter and edge angle before production. The same process covers Fisher and BOSS patterns.
What we can supply on a Western blade
Carbide, steel and poly edges, drilled to the pattern on your blade, for straight blades and V-plows. What we do not supply is the carrier assembly, the hydraulic system or the light bar — those stay with Western or with your dealer.
What to send before we confirm a Western pattern
Model family and year, blade width across the mounting face, edge height and thickness as fitted, hole spacing across three consecutive holes, and a photograph with a tape measure in frame. UltraMount identifies the truck-side interface; it does not describe the edge pattern, so the measurements come from the blade.
How we confirm the pattern
We map the hole positions, send back a drawing, and only cut after you approve it. For a pattern we already hold, the photograph confirms it in minutes. For one we do not, the drawing step is what prevents a wrong batch being cut twice.
When we will not quote a direct replacement
- The blade has been re-drilled or repaired after an impact — the published pattern no longer applies.
- The carrier is cracked around the bolt holes or dished; a new edge on a fatigued plate fails without warning.
- You need a documented OEM-equivalence claim. We quote to measurement, not to a brand guarantee.

Before you ask for a price
Send these five items and the quotation comes back size-confirmed rather than indicative: machine make and model, blade width measured across the mounting face, edge height and thickness as fitted, hole spacing centre-to-centre across three consecutive holes, and a photograph of the mount with a tape measure in frame.

Brand fitment confirmation checklist
Work through the list before you send anything: machine make, model and year; blade width at the mounting face; edge height and thickness as fitted; hole spacing across three consecutive holes; countersunk or plain hardware; and whether the mount has been repaired, welded or re-drilled.

Independent aftermarket supply
SENTHAI is an independent manufacturer of tungsten carbide and steel wear parts. We are not affiliated with Western, and we do not claim OEM equivalence or model-by-model compatibility. Every Western-pattern edge we quote is produced to dimensions measured on your blade, confirmed against a drawing before cutting.
Will an aftermarket edge fit my Western plow?
If the four measurements match: blade width, edge height, thickness and hole spacing. The brand and model year narrow it down; the pattern decides it.
Is the mounting system the same as the edge pattern?
No. UltraMount is how the plow attaches to the truck. The edge pattern is drilled into the blade itself and has to be measured separately.
Carbide or steel on a Western blade?
Carbide where the surface is abrasive and the hours are long. Steel on gravel and mixed routes, where impact chips a hard edge before abrasion wears it.
