NRH 4101-178 Extra Long Chrome Spring Flush Pull – 80kg Carbon Steel

NRH 4101-178 Extra Long Stroke Chrome Spring Flush Pull - Carbon Steel, 80kg Load, For Oversized Equipment

Extra‑large cabinet doors, heavy machinery access panels, and industrial HVAC units demand a handle with enough reach for gloved hands. The NRH 4101-178 delivers an extra long stroke with an overall length of 178mm - providing ample finger clearance even with thick gloves. Made from carbon steel with a bright chrome plating, it handles 80kg pull load while weighing 453g. An internal heavy‑duty stainless steel spring automatically retracts the handle flush with the panel when released - no protrusions, no snags. Ideal for large power distribution cabinets, heavy machine tool doors, railway vehicle electrical boxes, and port machinery control panels. NRH quality since 1996 ensures reliability.

Produced under ISO 9001, with 50,000‑cycle spring testing. REACH, RoHS available on request. OEM/ODM modifications (hole pattern, spring tension) welcome. 2D/3D CAD drawings supplied.

Critical cut‑out dimensions (see drawing): overall length 178mm, 4 mounting holes. Locating dimensions: 141.5mm, 136.5mm, 96mm, 93.5mm, 40.5mm, 36mm, 14.5mm, 8mm. Follow drawing precisely.

Extra Long Stroke - Designed for Oversized Equipment

At 178mm overall length, this handle offers significantly more finger clearance than standard spring pulls. Combined with an 80kg load rating, it's perfect for thick, heavy doors where operators wear gloves. The chrome finish resists oil, dirt, and corrosion, making it ideal for heavy industrial environments.

Applications - Built for the “Big Stuff”

• Large central power distribution cabinets / switchgear - heavy doors need long‑reach handles
• Heavy CNC machine tool guards - gloved‑hand operation, long stroke prevents finger pinch
• Industrial HVAC / central air handling units - large access doors, auto retract ensures proper sealing
• Railway vehicle electrical cabinets (high‑speed trains, subways) - tight spaces, flush design, long reach
• Port machinery / crane control panels - salt‑spray resistant chrome, long stroke for gloved hands
• Special vehicle service hatches - auto retract prevents snag hazards

How It Works - Big Spring, Solid Retraction

Inside is a large‑diameter stainless steel compression spring, preloaded for longer travel. Normally recessed. Pull to extend approx. 50-60mm; release, and the spring instantly returns the grip flush. Installation requires a matching cut‑out (see drawing) and four rear screws.

Key Advantages

• 178mm overall length - extra long stroke for gloved‑hand operation
• 80kg rated load - handles heavy doors with safety margin

Why Oversized Equipment Chooses NRH Extra Long Pulls

The NRH 4101-178 fills the gap left by standard spring pulls (typically ≤160mm). It has been adopted by major power equipment, heavy machinery, and railway manufacturers. If you need a flush‑mount, auto‑retracting handle with extra long reach for oversized doors, this is the proven solution.
