The Simpson THGQH5.50-SDS is a heavy-duty girder truss hanger engineered for demanding structural connections where a girder truss - or a structural composite lumber beam attached to a girder truss - must be securely supported. As a lower-cost alternative to traditional bolted hangers, this hanger leverages Strong-Drive SDS Heavy-Duty Connector screws to deliver high load capacities without the complexity of bolted installations. Built from thick 3-gauge steel and finished in Simpson Strong-Tie gray paint, the THGQH5.50-SDS is manufactured in the United States and offers both minimum and maximum fastener quantities to accommodate a wide range of design requirements.

Key Features

• SDS Screws Included for Load Transfer: Strong-Drive SDS Heavy-Duty Connector screws are included to help transfer the load between the plies of the supporting girder when they penetrate all plies.
• Higher Load Potential: Increased allowable loads are available when a wider vertical web is used, giving engineers and contractors design flexibility.
• Skewable Design: Various models may be skewed up to 45 deg., accommodating non-perpendicular framing conditions.
• Generous Seat Width: 5-1/2 in. seat width provides a stable, well-supported bearing surface for the carried member.
• Tall Profile: 25 in. height is suited for large girder truss applications requiring substantial bearing engagement.
• Heavy 3-Gauge Steel Construction: Manufactured from 3-gauge steel for exceptional strength and rigidity in high-load structural applications.
• Durable Finish: Simpson Strong-Tie gray paint finish provides protection and a clean, professional appearance.
• Screw-Based Installation: Uses Strong-Drive SDS screws rather than bolts, simplifying installation and reducing labor compared to traditional bolted hanger systems.
• Flexible Fastener Quantities: Minimum and maximum fastener quantity options allow the hanger to accommodate varying structural design needs.
• Made in the USA: Manufactured in the United States.
