HES 310-4-1 24D 630 Electric Strike
This heavy-duty electric strike is designed for access-control systems that require fail-secure operation at 24 V DC. It suits commercial and industrial doors using mortise or cylindrical locksets where security must be maintained during power loss. The stainless-steel construction and Grade 1 rating support extreme-duty applications.
Integration with door frames and power
The strike mounts in metal or wood frames with a faceplate measuring 1 1/2 in wide by 13 3/8 in high and 3/4 in deep. It accepts a 3/4 in bolt throw and operates on 24 V DC, freeing the specifier from sourcing a separate AC supply. The fail-secure mode keeps the door locked when power is removed, simplifying safety compliance.
Upgrade from standard-duty strikes
This unit replaces lower-grade strikes that cannot withstand 1,500 lb pull force or 1,000,000 test cycles. The jump is justified when the opening demands fire-rated hardware and industrial-grade durability in a stainless-steel finish. It is not for residential light-duty use or for frames that cannot accommodate the listed faceplate dimensions.

Questions about this item
How long does the 24VDC electric strike stay cool under continuous heavy-duty operation?
The HES 310-4-1 is built with stainless steel construction for industrial-grade heat dissipation during sustained 24VDC use, rated for 1,000,000 cycles.
What is the power draw and heat output when the strike runs all day on 24VDC?
Operating at 24VDC, the fail-secure strike draws minimal current while the stainless steel body manages heat across 1,000,000 rated cycles.
Which mortise or cylindrical lockset and 24VDC power supply must I already have to install this strike?
The strike fits standard mortise or cylindrical locksets with a 3/4 inch bolt throw and requires a 24VDC supply for fail-secure operation.
