90 Degree Stainless Steel Handrail End Cap for Stair

Why ESANG’s 90 Degree End Cap Solves Your Multi-Size Handrail Problems

Generic 90-degree end caps force you to stock multiple sizes (wasting time and money) or settle for ill-fitting options. ESANG’s version targets this “one-cap-for-all” pain point, plus other size-specific issues:

• No More Size Mismatches for 38.1mm/42.4mm/50.8mm Tubes: Unlike single-size caps, we offer three precision-cast variants—each tailored to fit 38.1mm ±1mm, 42.4mm ±1mm, or 50.8mm ±1mm tubes exactly. No gaps, no sanding, no modifying tubes to fit the cap—saves hours of rework on mixed-size projects (e.g., stair rails with 38.1mm top rails and 50.8mm posts).

• Flimsy Construction? Not Anymore: Many multi-size cap lines use thin stamped metal for smaller diameters (38.1mm/42.4mm), leading to bending. Our end caps—regardless of size—use 3mm thick cast stainless steel (AISI 304) for 2x the impact resistance of stamped alternatives. Even the 38.1mm variant won’t warp under pressure (e.g., kids leaning on stair rails).
• 600Grit Polish That’s Consistent Across All Sizes: Cheap end caps sacrifice finish quality for smaller sizes (dull 400Grit for 38.1mm/42.4mm). Our caps—from 38.1mm to 50.8mm—feature uniform 600Grit polished surfaces (mirror-like shine, scratch-resistant). They look cohesive on mixed-size railings, no matter the tube diameter.
• Satin: Brushed matte finish (180Grit process) that hides fingerprints, smudges, and minor scratches—ideal for high-traffic areas (apartment stairwells, commercial lobbies) or industrial-style designs.
  Both finishes are uniform across all sizes—no “cheap-looking” small caps ruining your railing’s aesthetic.

• Weldable + DIY-Friendly for All Sizes: Some end caps only offer DIY assembly for small tubes or welding for large ones. Ours works for every size: weldable for permanent commercial installs (e.g., office stairwells with 50.8mm tubes) or DIY-assemblable with adhesive (e.g., residential balconies with 38.1mm rails). No more compromising on installation method.

Why ESANG Outperforms Generic Multi-Size End Caps

Generic multi-size end caps cut corners on smaller diameters (thinner metal, cheaper polish). Here’s how ESANG’s version stands out—for 38.1mm, 42.4mm, and 50.8mm alike:

• Uniform Quality Across All Sizes: Unlike competitors who use stamped metal for 38.1mm/42.4mm caps, we use gravity casting for every variant. This ensures 3mm thick walls (no weak spots) and consistent strength, regardless of tube diameter.

• 600Grit Polish for Every Size: Most brands offer 600Grit only for 50.8mm caps; we extend this luxury finish to 38.1mm and 42.4mm. The result? Mixed-size railings (e.g., 38.1mm top rails + 50.8mm posts) look cohesive, no “cheap” small caps ruining the aesthetic.

• Satin Finish That’s Actually Durable: Cheap satin caps peel or dull after cleaning. ESANG’s satin uses a mechanical brushing process (not chemical coatings) that withstands frequent wiping with soap and water—no fading or peeling, even in high-moisture areas (e.g., poolside rails).

• Anti-Vandalism Adhesive for All Variants: We include a high-tack, weatherproof adhesive pad with every cap (bulk orders) — even 38.1mm. This bonds the cap to the tube, preventing theft or tampering in public spaces (e.g., apartment stairwells with 42.4mm rails).

• Material Verification for Every Batch: Every cap—regardless of size—undergoes XRF testing to confirm 18% chromium/8% nickel (true AISI 304). We provide a material certificate with bulk orders, so you know small and large caps meet the same standard.

Installation Guide: Easy for Any Size (38.1mm/42.4mm/50.8mm)

1. For Weldable Installs (Commercial/Heavy-Duty)
2. Prepare the Tube: Cut your 38.1mm/42.4mm/50.8mm tube to length, then clean the end with a wire brush (removes rust for strong welds).
3. Align the Cap: Slide the matching-size end cap onto the tube until flush. Use a level to confirm the 90° angle matches your railing’s corner.
4. Weld Securely: Weld the cap’s base to the tube at 3 points (top, bottom, 90° bend) for even strength. Let cool, then wipe with a cloth to reveal the polish.
