Description
The Spike is a one-piece, vibration-resistant anchor for use in concrete blocks or stone. Several head styles, including tamperproof versions, and anchor materials are available. The Spike anchor is formed with an s shaped configuration at the working end of the anchor to create an expansion mechanism. Since the anchor is pre-formed, there is no secondary tightening operation required which greatly reduces the overall cost of an anchor installation.
FEATURES:
- Tested in accordance with ASTM E488 and AC01 criteria
- Pre-expanded anchor design allows for easy installation
- Mushroom and flat head Spike anchors are tamper-proof
- Forming Spike, which is removable, can be used for temporary installations
- Pipe and tie-wire Spike is a simple to install alternative to direct fastening (e.g. powder actuated)
