112-006 08100-4

At new sills and thresholds installed on existing floor materials, level existing materials with grout as required to 1 make proper substrate for installation of new sill or threshold. 2 Install frames accurately in position, plumbed and aligned to Door and Hardware Institute standards, and braced 4 securely until permanent anchors are set. Anchor frames securely to floor and at jambs. Furnish necessary clips, 5 fastenings and anchorages, and conceal unless otherwise noted. Weld all field joints, grind smooth, and fill with 6 body putty to completely conceal seams and to form a smooth, unbroken finish surface. 7 Spot grout at all jambs of frames set into metal stud construction; this work is included under Section 09250. 9 Where frames are anchored with bolts, bolts shall be countersunk, and surfaces shall be made smooth with putty. 11 Install fire-rated frames in accordance with NFPA Standard No. 80. 12
