ACI Adhesive Anchor Installer Certification Practice Exam

What does it mean if a capsule is described as bi-directional?

1. It can only be inserted one way

2. It can be used with multiple adhesives

3. Either end can be inserted into the hole

4. It can be reused for future installations

The correct answer is: Either end can be inserted into the hole

A capsule described as bi-directional indicates that either end of the capsule can be inserted into the drilled hole. This is a design feature that enhances the versatility and usability of the adhesive anchor system. It allows for greater flexibility during installation, as the installer does not have to worry about which end of the capsule is facing outward when loading it into the hole. This can lead to efficiencies on the job site by reducing time spent on ensuring proper orientation and potentially simplifying the installation process. The ability to insert either end is particularly useful in situations where space is limited or where visibility into the hole is obstructed. It allows for quicker adjustments during the installation process without compromising the effectiveness of the adhesive. Other options do not align with the concept of bi-directionality. The first option implies a singular direction for insertion, which is contrary to the principle of being bi-directional. The second option suggests compatibility with different adhesives, which is not necessarily related to the directional nature of the capsule. The fourth option implies reusability, which is generally not applicable to adhesive capsules, as they are typically designed for one-time use.
