The embedded truss anchor series provides an engineered method to properly attach roof trusses to concrete and masonry walls. The products are designed with staggered nail patterns for greater uplift resistance. Information regarding the use of two anchors on single- and multi-ply trusses is included. The TSS, a companion product of the META, provides a moisture barrier between the concrete and truss. The preassembled unit is riveted with no height adjustment. MATERIAL: HHETA-14 gauge; HETA-16 gauge; HETAL-strap 16 gauge, truss seat 18 gauge; META-18 gauge; TSS-22 gauge. FINISH: Galvanized. Some products available in Z-MAX; see Corrosion Resistance, page 6-7. INSTALLATION: Use all specified fasteners. See General Notes. The META, HETA and HHETA are embedded 4" into a concrete beam or grouted block wall; HETAL is embedded 5 ". Do not drive nails through the truss plate on the opposite side of the truss, which could force the plate off the truss. The TSS moisture barrier may be preattached to the truss using 6d commons.

Refer to page 13 for further explanation. 2.Five nails must be installed into the truss seat of the HETAL. 3.Parallel-to-plate load towards face of HETAL is 1975 lbs. 4.Lateral loads for products noted in the table are based on a minimum installation of 12 nails and the strap wrapped over the heel. 5.Minimum f'c is 2,000psi. HETA20 (HHETA similar) HETAL Typical HETA20 with TSS Installation 6. On the META20, HETA20 and HHETA20, it is acceptable to use a reduced number of fasteners provided that there is a reduction in uplift load capacity. See example on page 158. Lateral loads do not apply for reduced nailing. 7. Minimum spacing is 2 times the embedment depth for full load. 8. See instruction to the Designer page 15 for loads in multiple directions. 9. Single ply trusses may use either 10dx1 (0.148 dia. x 1 or 16d (0.162 dia. x 3 nails. 2 or 3 ply trusses shall use 16d (0.162 dia. x 3 nails. 10. NAILS: 16d 0.162" dia. x 3 long, 10dx1 0.148" dia. x 1 long. See page 16-17 for other nail sizes and information. Available with additional corrosion protection. Check with factory.
