SQC2M-S-MLM

Product Description

The SQC2M-S-MLM is a CNC milled aluminum swivel coupler that connects 2-inch square tubing to 1.66–2.00 inch OD round pipe or truss tube in a single rated fitting — the hardware solution for hybrid structures where square tube and round pipe meet. The Mega Coupler half grips the round tube across the full 1.66 to 2.00 inch OD range, covering 1-1/4 inch nominal pipe and standard 2-inch OD truss tube. The square coupler half captures the 2-inch square chord. The swivel connection lets the installer set the working angle before locking with the socket head cap screw into a hex milled pocket secured by a nylock nut — and when the application requires a fixed connection, alternate bolt positions convert the fitting to a rigid 90-degree configuration. Fabricated from 6061-T6 aluminum alloy, CNC milled with a natural brushed finish. Solid aluminum wing nut tabs are 3/4-inch wrench compatible. Rated at 1,100 lb working load limit. Backed by a 1-year limited warranty against manufacturing defects.

Key Features

• Round-to-square hybrid connection: Bridges 1.66–2.00 inch OD round pipe or truss tube to 2-inch square tubing in a single CNC milled fitting — no custom fabrication, no separate clamp and angle bracket at the transition point.
• Swivel or rigid 90-degree configuration: Default swivel mode lets the installer dial in the working angle before locking. Alternate bolt positions convert the same fitting to a fixed 90-degree connection when the application requires it.
• Socket head cap screw lock into hex milled pocket: The locking mechanism seats into a precision milled pocket with a nylock nut — positive engagement that resists backing out under dynamic loads.
• Solid aluminum wing nut tabs: 3/4-inch wrench compatible — not plastic, not stamped steel. The tabs take full wrench torque without deforming.
• 1,100 lb working load limit: Rated for overhead lighting, signage, and monitor loads in production, exhibit, and theatrical applications.
• 6061-T6 aluminum, CNC milled: Precision machined from structural aluminum alloy — consistent fit, consistent load path, consistent inspection across every unit in inventory.
• Natural brushed finish: Clean professional appearance in both black grid and bright overhead environments.
• 1-year limited warranty against manufacturing defects.

Who It's For

• Production riggers bridging square truss to round pipe systems: Your overhead structure combines square box truss with standard round Schedule 40 pipe and you need a rated connection point where the two profiles meet. The SQC2M-S-MLM handles that transition in a single fitting — the Mega Coupler half grips the round pipe or truss tube, the square coupler half captures the 2-inch chord, and the swivel lets you set the angle before locking with the socket head cap screw. One cataloged piece replaces a field-fabricated adapter at every hybrid connection in the rig.
• Trade show exhibit structural fabricators: Your exhibit builds combine square truss overhead grids with round pipe uprights, drape systems, or banner arms, and you need a rated fitting at the transition point that doesn't require custom work on the show floor. The SQC2M-S-MLM eliminates that fabrication step — the 1,100 lb working load limit covers the overhead lighting, signage, and monitor loads typical of a 10x10 or 10x20 island exhibit, and the swivel configuration handles the angle variations that come with different booth footprints.
• Theatrical and film set riggers: Your overhead grid uses both round pipe and square tube, and the set designer's specifications call for a connection at a specific angle between the two systems. The swivel mode lets you hit that angle precisely before locking, and when the connection needs to stay fixed after tightening, the rigid 90-degree configuration option is available from the same fitting without additional hardware. One coupler covers both use cases across the same production.
• Rental house inventory managers: Your shop stocks both square truss and round pipe systems, and clients regularly mix formats in the same build. The SQC2M-S-MLM gives you a cataloged, load-rated transition fitting that you can track, inspect, and replace on the same maintenance cycle as the rest of your clamp inventory — no custom fabrication required for each client, no improvised connection that falls outside your documented load ratings.

Compatibility — Read Before You Buy

• Round tube range: The Mega Coupler half fits 1.66 inch to 2.00 inch OD round pipe and truss tube only — covering 1-1/4 inch nominal pipe and standard 2-inch OD truss tube. Do not use on tubing outside this OD range.
• Square tube size: The square coupler half accepts 2-inch square tubing only. Not compatible with 1.5-inch or other square tube profiles.
• Locking hardware: The socket head cap screw requires a hex key for tightening. The wing nut tabs require a 3/4-inch wrench. Confirm both tools are on hand before installation.
• Swivel vs. rigid: The swivel mode is the default configuration. Rigid 90-degree requires repositioning the bolt to the alternate hole positions — verify the required configuration before installing under load.

Safety and Engineering

• Working load limit: Do not exceed the rated working load limit of 1,100 lb. This rating applies to the coupler connection only — verify the load rating of all connected structural elements independently.
• Pre-use inspection: Inspect the wing nut tabs, socket head cap screw, nylock nut, and milled pocket before every use. Remove from service immediately if any component shows deformation, thread damage, or cracking.
• Locking confirmation: The socket head cap screw must be fully seated in the hex milled pocket and the nylock nut fully engaged before any load is applied. A partially tightened fitting is not a secured fitting.
• Secondary safety: The use of safety cables is mandatory for all overhead rigging applications.
• Engineering review: The purchase of this product does not authorize or approve a specific installation or use. A licensed professional engineer shall review all structures, rigging plots, or other coupler uses.
