100 alpineitw.com (800) 521-9790 AD20A (AD14A Typical/W = 3 1 ⁄2") AD15 AD ADA ADB ANCHOR DOWNS Design Features… offer the builder a lighter anchor down device with greater load capacity at a more affordable price… applications include: • AD/ADA/ADB Series… no standard washer requirement with anchorage bolts. Washer location is indicated on item drawings. • ADA Series… no more inspection problems, as the ADA series has a load transfer plate formed and pressed into to the base. • Uses include anchoring vertical wood members to foundation to resist uplifts due to overturning. • Installation can be made horizontally for seismic ties. PRODUCT CODE WASHER SIZES MATERIAL OUTSIDE DIAMETER (INCHES) AD2 1 3 ⁄4 10 ga AD5 2 9 ga AD6 2 1 ⁄2 8 ga AD7 2 3 ⁄4 8 ga AD9 2 3 ⁄4 8 ga AD12 2 3 ⁄4 8 ga AD15 3 8 ga Fourteen configurations meet a variety of size and load specifications, with the location of the anchor down on the stud (D) measured at 7x's the diameter of the bolt above the plate or the self-jigging. Minimum required distance is automatically maintained. Material… 3 ⁄16", 1 ⁄4" and 3 ⁄8" steel, depending on size and load requirements. Finish… AD, AD14A and AD20A SUPERSPEED ® gray paint. Finish…ADA and ADB 7 ga. galvanized steel. Loads… have been increased by 33 1 ⁄3% for seismic applications. Special… features of the ADA/ADB include: • ADB series requires no load transfer plate due to increased thickness of body part. • Single piece design results in higher capacity. • Load transfer plate eliminates the need for seat washer. • Stud or post bolts are factory lined-up by welding (AD14A where the straps overlap). This reduces labor costs and damage to the machine bolt threads; more importantly, the weld acts to unite the parts as a single unit. • Self-jigging design allows for flush surface installation to insure code-required 7 bolt diameter spacing from the end of the member. • There are fewer inspection problems. • Anchor down may be used to transfer tension loads between floors, to the purlins to masonry or concrete, to the wood wall sections to vertical concrete or masonry or used for overturn requirements and either applications to transfer tension loads. Anchor bolt nuts, should be finger-tight plus 1/2 to 1/3 turn with a wrench as stated by ASTM test standards for anchor bolts.
