Concealed 3-D Adjustable Hinges 1131 Series, 6-5/16" x 1-1/4", Silver

Concealed 3-D Adjustable Hinges 1131 Series Use

Concealed 3-D Adjustable Hinges 1131 Series, 6-5/16 x 1-1/4, Silver are invisible hinges that sit recessed in the door and frame, so the hinge stays hidden while the door operates. The design suits doors with a minimum thickness of 1-1/2 inch and up to 39-3/8 inch wide, which aligns well with many interior and specialty doors where a flush, clean look is important. A fluid 180 degree opening allows the door to swing fully, helping doors clear trim and casings where full access is required. The hinges are manufactured in zinc to resist oxidation, which supports long-term performance in typical interior environments. Testing for a minimum 200,000 opening and closing cycles shows the hinge is designed for repeated use over time. A load capacity of 265 lb, or 120 kg, allows the hinge to support substantial door weights in appropriate applications. UL certification confirms that the hinge has been evaluated against recognized safety standards.

Key Functional Details For Hinge Selection

• The hinge size of 6-5/16 inch by 1-1/4 inch gives a compact, elongated footprint, which helps fit into a precise mortise while distributing load along the door edge.
• Suitability for doors of 1-1/2 inch minimum thickness supports use on thicker, solid doors, which matters when planning mortise depth and structural edge strength.
• Use on doors up to 39-3/8 inch wide ties hinge choice to typical residential and commercial door widths, helping align hinge spacing and count to standard layouts.
• A rated load capacity of 265 lb, or 120 kg, allows the hinge to carry heavy doors within that range, which supports applications using dense cores or specialty cladding.
• Testing for a minimum 200,000 opening and closing cycles indicates the hinge is designed for frequent operation, which is relevant for high-use doors in busy areas.
• Manufacture in zinc to resist oxidation supports surface integrity in standard interior conditions, which matters for long-term appearance and movement at the pivot points.
• Availability in 10 different finishes, with this version in silver, supports matching visible hinge edges to surrounding hardware and trim where the hinge gap is exposed.

Installation And 3D Adjustment Details

The hinge is described as easy 3D adjustable, which means the hinge provides three-directional adjustment after installation, helping align the door within the frame without re-cutting mortises. Easy installation with symmetrical mortising for door and frame means the same cut pattern is used on both sides, simplifying layout and routing when preparing multiple openings. A fluid 180 degree opening allows the door to swing fully open around the hinge axis, which can help with clearance in corridors or tight reveals. The invisible hinge format places the mechanism recessed within the door and frame, so careful mortising directly supports smooth movement and consistent reveals once the adjustments are made.

Using The 1131 Series Hinge In Real Projects

Where This Invisible Hinge Format Is Applied

This product is categorized as an invisible hinge within the broader hinges, invisible and recessed hinges class, so it is intended for projects where the hardware should stay out of sight when the door is closed. Suitability for doors of 1-1/2 inch minimum thickness and up to 39-3/8 inch wide positions it for use on substantial interior doors, specialty panels, or concealed passage units that match those dimensions. The 160x32 hinge designation, together with the 6-5/16 inch by 1-1/4 inch size, identifies a relatively tall, narrow hinge body, which is useful where the mortise can run vertically along the door edge without consuming excessive width. The silver finish variant can coordinate with other silver-toned components around the opening, keeping visible edges at the gap consistent with nearby hardware. Manufactured in Italy under the Peter Meier, Inc. brand, the hinge ties into a hardware system recognized in woodworking and architectural projects.

How 3D Adjustment And Testing Support Results

The easy 3D adjustable feature lets the installer fine-tune the door position in three directions, which helps dial in margins and flushness after the mortises are cut. This capability reduces rework on the door or frame because adjustments can be made at the hinge rather than altering the wood. Symmetrical mortising for door and frame means a single routing pattern can be repeated, which improves consistency when working on multiple doors and frames using the same hinge layout. Testing for a minimum 200,000 opening and closing cycles shows the hinge mechanism is designed to operate repeatedly without binding under normal use, which supports long-term alignment when combined with the adjustable design. The load capacity of 265 lb, or 120 kg, allows the hinge to carry heavier doors within that rating, giving flexibility to use denser materials or added layers without exceeding the hinge specification. UL certification adds a documented evaluation against recognized safety and performance criteria, which can support project requirements where listed hardware is preferred. Zinc construction that resists oxidation helps preserve the hinge body and moving joints over time in typical interior environments, which supports smoother operation across the tested cycle range.

Common Questions About The C1131SIL Hinge

Choose The Right 160x32 Concealed Hinge

The 160x32 concealed hinge in the 1131 Series, identified by manufacturer part number C1131SIL, combines a 6-5/16 inch by 1-1/4 inch body, easy 3D adjustment, and a 265 lb load capacity. Suitability for 1-1/2 inch thick doors up to 39-3/8 inch wide aligns with many interior door designs where an invisible hinge look is required.
