The Stainless Steel Handrail Reducer (Internal Fit) is a precision-engineered adapter fitting designed for transitioning between handrail sections of different diameters. Featuring a stepped, tapered cylindrical structure, this internal reducer connects larger base pipes to smaller handrail tubes while maintaining a flush, concealed line across balustrade installations. By mounting internally within the larger pipe section, it eliminates visible external sleeves, providing a clean architectural transition with high structural stability.
Engineered to fit standard tube configurations such as Ø 25.4 mm × 1.5 mm and Ø 50.8 mm × 1.5 mm, this connector features a smaller upper diameter (Ø 1) of 19 mm or 25 mm and a larger lower base diameter (Ø 2) of 38.1 mm or 50.8 mm. The transition neck provides a working height extension (A) of 81 mm to ensure proper alignment and load dispersion. Cast and machined from high-grade stainless steel (AISI 304, AISI 316, or Duplex SS 2205) and available in satin (matte) or mirror-polished finishes, these durable handrail fittings serve as ideal Handrail Support accessories for residential, commercial, and marine railing systems.

Q1: What is the purpose of an internal fit Handrail Reducer?
A: An internal fit Handrail Reducer connects two handrail tubes of different diameters while keeping the outer transition smooth and concealed, offering a sleek architectural appearance without bulky external joints.
Q2: How does this reducer mount into the handrail system?
A: The lower base sleeve ($\varnothing 2$) inserts internally into the larger pipe section, while the upper extension ($\varnothing 1$) connects to the smaller diameter handrail tube, providing a aligned, rigid connection.
Q3: Which tube sizes and wall thicknesses are supported?
A: The reducer supports tube sizing configurations including Ø 25.4 mm × 1.5 mm and Ø 50.8 mm × 1.5 mm, with upper diameters (Ø 1) of 19 mm or 25 mm and lower base diameters (Ø 2) of 38.1 mm or 50.8 mm.
Q4: Which material grade should be selected for marine or coastal applications?
A: For marine, coastal, or harsh outdoor environments, select AISI 316 or Duplex SS 2205 stainless steel for maximum resistance against pitting and atmospheric corrosion.
