Why Choose the nVent HOFFMAN ESFS278 Side-Mounted Swing Frame?
The nVent HOFFMAN ESFS278 is a full-height side-mounted 19-inch swing frame designed to provide additional equipment mounting capacity inside compatible floor-standing electrical enclosures. Intended for 1400 mm high enclosures, it provides 27 U of rack mounting capacity while allowing convenient access to both the front and rear of installed components.
The ESFS278 uses a rigid W-shaped frame construction suitable for heavy equipment and incorporates zinc-plated 19-inch vertical profiles that provide direct earthing of mounted components. Standard 130° hinges allow the frame to swing open from either the left or right, while an adjustable upper hinge helps ensure accurate alignment during installation.

Flexible 19-Inch Equipment Mounting for Floor-Standing Enclosures
Side-mounted swing frames provide an effective way to integrate 19-inch rack equipment into industrial floor-standing enclosures while retaining access to equipment installed behind the frame. When the ESFS278 is opened, technicians can access both sides of the rack-mounted components as well as equipment positioned deeper inside the enclosure, simplifying installation, wiring and maintenance.
The ESFS278's hinged construction also helps optimise usable equipment depth. Compatible accessories include ESFB transversal support bars for enclosure mounting, SFMP depth mounting plates for additional support and cable routing, and ESFH180 hinges where full 180° opening is required.
