Anchors set too shallow or too close to the edge of a slab or tube will cause the concrete to crack and pop loose, rendering the anchor useless. One solution is Ankr-Tite's Power-Sert drop-in anchor, which works in combination with the company's Inject-Tite epoxy adhesive to form a high-strength bond in relatively shallow holes and tight spacing patterns. Small overbore tolerances allow predrilling through base plate or machinery mounting holes without moving the piece to be attached. And because the anchors hold by friction until the epoxy sets, attachments can be made immediately. According to the manufacturer, Power-Serts display higher resistance to seismic loading and vibration than most drop-in anchors. The anchors are threaded at the top to accept
