CFC Gate Hardware & Access Control 1

Question 1

What type of hinge is most commonly specified for heavy commercial swing gates requiring post-installation adjustment?

Accepted Answer

Weld-on adjustable hinge

Answer

Weld-on adjustable hinges provide the structural strength and three-way adjustability needed for heavy commercial swing gates.

Question 2

Which latch type offers the greatest security for a single swing gate by allowing locking from both sides of the fence?

Accepted Answer

Padlock-compatible double-sided latch

Answer

A padlock-compatible double-sided latch enables access from inside and outside while also accepting a padlock for added security.

Question 3

What is 'gate sag,' and which component is typically installed to prevent it?

Accepted Answer

Gate dropping at the latch end; an anti-sag kit or tension rod

Answer

Gate sag occurs when the unsupported latch end of a gate droops under its own weight; anti-sag kits with diagonal tension rods counteract this force.

Question 4

For a double swing gate system, what component ensures the two gate leaves close in the correct sequence?

Accepted Answer

Gate coordinator

Answer

A gate coordinator mechanically links both leaves so the active (latch) leaf always closes after the passive (strike) leaf, ensuring proper latching.

Question 5

What is the primary function of a gate stop installed on a swing gate?

Accepted Answer

To prevent the gate from opening too wide and to protect hinges from over-extension

Answer

Gate stops limit the swing arc to prevent hinges from being over-extended, which would cause premature failure of the hinge hardware.
