SCISSOR TYPE 4″ PIVOT HINGES

Product Description

Scissor pivot hinges are the hardware upgrade your heavy-door infrastructure needs. This hinge solves door sagging, binding, limited swing, and premature wear. It delivers robust load distribution, smooth operation, and long-term reliability.

Core Specifications

The 4-inch scissor-type pivot hinge features two interconnecting arms that pivot on multiple points for smooth, stable door movement. The scissor mechanism provides superior load distribution compared to standard butt hinges. This 4-inch size supports door weights of 40-80kg per hinge set, suitable for commercial steel doors, heavy wooden entrance doors, and industrial partition systems. Designed for doors of standard thickness.

Construction and Materials

Heavy-duty steel or stainless steel construction provides exceptional strength, corrosion resistance, and dimensional stability. Precision-machined and heat-treated components resist deformation under heavy loads. Corrosion-resistant finishes include zinc-plated, powder-coated, or polished stainless steel.

Scissor Mechanism and Performance

The compound hinge system connects the door to the frame through two interconnected arms, distributing weight evenly and reducing stress on any single pivot. This results in smoother operation with less wear on hinge pins and bushings. The hinge provides a full opening range of up to 180° in some configurations, significantly more than standard butt hinges. The reduced swing radius requires less clearance space.

Adjustability and Installation

3D adjustment during installation allows fine-tuning of door alignment, gap spacing, and swing clearance. This compensates for minor architectural imperfections without extensive structural modifications. The hinge is available in flush-mount and surface-mount configurations. Pre-drilled holes accommodate M6 or M8 screws. An installation template and comprehensive instructions are included.

Durability and Quality

QA testing includes load testing, cycle testing, corrosion resistance testing, and impact testing. Steel resists bending, twisting, and fatigue through thousands of cycles. Precision-machined pivot pins and bushings maintain tolerances over time. The finish resists chipping, scratching, and corrosion.
