SPACING
Anchor spacing should be a minimum of 2' apart for proper performance.

DRYWALL ON BLOCK OR CONCRETE
To use E-Z Ancor® fasteners in drywall installations mounted over cinder block or concrete (such as basements or residences in southern coastal areas) if the opening behind the drywall is narrow (3/4), you can snip 1/2 off the drilling end and still install the anchor. Although this is not optimal, the anchor will retain the strength to create its own hole.

SCREWDRIVER FIT
When installing anchors that have a recess in the head for use with a Phillips screwdriver, ensure that the screwdriver fits snuggly and firmly into the recess and does not wobble excessively. Excessive wobbling, or any instability when turning screws or anchors, makes the installation much more difficult.

USING MULTIPLE ANCHORS
The anchor’s load performance is determined by the anchor’s ability to hold the immediate surrounding drywall surface in a 1' diameter. As such, using more than one anchor doesn’t mean the load performance can be multiplied by the number of anchors used. Although there is some minor increased holding power gained from “load sharing” between anchors, the amount is negligible.

WORKING VS. STATIC LOAD
Installations involving a “working or moving load,” rather than a “static load,” need to be considered differently when evaluating appropriate anchor strength. A towel bar or a clothing rack are examples of working load applications versus a picture frame, mirror or thermostat, which are examples of static loads. The movement, vibration or shocks applied to working load applications can cause anchors to fail at lower values.
