National Mfg N104-752 Double Splice Bracket Galvanized

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N104-752 is a galvanized double splice bracket designed for mounting a double run of box rail on buildings with corrugated metal siding. The adjustable design accommodates field fitting, making it suitable for installers working with 5114 or 5116 box rail systems. Sold in a package of two, this bracket provides a corrosion-resistant fastening solution for exterior structural applications. Contractors and tradespersons working on agricultural, commercial, or industrial buildings with corrugated metal exteriors will find this bracket a direct fit for box rail splice mounting tasks.

This bracket is intended for use on buildings clad in corrugated metal siding where a double run of box rail must be securely mounted. The adjustable feature allows the bracket to compensate for the profile variation of corrugated panels, reducing the need for shimming or custom fabrication on the jobsite. It is commonly installed during barn door hardware, sliding gate, or overhead track system installations on metal-sided structures.

Use appropriate corrosion-resistant fasteners to maintain the integrity of the galvanized finish. Refer to local building codes for structural attachment requirements when mounting rail systems to metal-clad buildings.
