Extruded Aluminum Enclosure With Plastic Corner Protectors

Extruded Aluminum Enclosure with Plastic Corner Protectors

If you have ever unboxed an extruded aluminum enclosure and found a scratched corner after rough delivery, you already know why plastic protective corners matter. The corner is the first point of impact during handling: the extrusion carries EMI shielding, heat dissipation, and rigidity, while the protector takes the knock so the aluminum itself never dents.

Why add corners to an aluminum extrusion housing?
Aluminum extrusions for electronics give a clean, rigid chassis that slides over a PCB, but a bare profile exposes four sharp corners. On the bench, on the line, or in a cabinet, those corners chip the anodized finish, catch wiring harnesses, and cut hands. A fitted plastic cap turns the impact point into a replaceable consumable, so the chassis survives repeated shipments and vibration-heavy equipment without cosmetic damage — exactly why buyers looking for custom aluminum enclosures electronics keep asking for this variant.

Four in-stock models with protectors installed
SC-FT75x35-K158 — 75 x 35 mm, compact chassis for sensor nodes and small transmitters
SC-FT120x40-K116 — 120 x 40 mm, popular unit for PLC modules and communication boards
SC-FT90x35-K73 — 90 x 35 mm, narrow profile for handheld or wall-mounted controllers
SC-FT80x40-K61 — 80 x 40 mm, balanced size for power modules and instrument housings
Each is a finished extruded aluminum enclosure box in our warehouse, anodized and ready for drilling.

Corner colors
Corners come in red, blue, yellow, gray, and black. Color coding solves a maintenance problem: yellow on high-voltage units, red on alarms, blue on sensor nodes, gray or black for a neutral look. Mix colors across a batch, or fit different colors at each end.

440+ stock profiles, no mold fee, 1-piece MOQ
We are an aluminum enclosure manufacturer running more than 440 sets of extruded aluminum enclosures in stock. These are existing public dies, so you pay no mold fee and we ship from 1 piece — no batch penalty for a prototype, field replacement, or small lot. Around your PCB we add custom mounting holes, threaded bosses, and cutouts on CNC centers (tolerance +/-0.01 mm), custom end caps matched to your cable entry, display, or connectors, plus free design service: send the PCB drawing or hand sketch, our engineers return a layout review before production.

Asking where can I buy bulk aluminum enclosures with high ip ratings for harsh environments? Gasketed end caps support IP65/IP68 sealing for extruded aluminum outdoor enclosures, junction boxes, and equipment exposed to rain and dust. The protector takes mechanical abuse; the gasketed cap takes ingress.

Built for electronics, built to spec
These profiles sit under aluminum extrusions for electronics enclosures and electronics extrusion parts housing — a chassis built for a circuit board, not generic sheet metal. Need a custom aluminum enclosure for a new device? We work from your internal dimensions. Need aluminum enclosure custom high quality for a customer-facing product? We match anodize finish, corner color, and laser marking to your brand. Browse our custom aluminum enclosures; the British spelling extruded aluminium electronic enclosures names the same family. Our extruded aluminum enclosures electronics line covers prototypes and bulk repeats; aluminum extrusions for outdoor enclosures come from the same die family with weather-sealed end caps.
