Field notes from Ontario installs
Judged by its walls, Ontario is two cities sharing one name. The historic spine along Euclid Avenue, the grand boulevard the founders built for their model colony, is lined with 1910s-to-1950s Craftsman bungalows and early ranch homes, nearly all of them lath-and-plaster over wood stud. The Ontario Mills district, the airport corridor, and the north end are newer wood-frame stucco tract over plain drywall. The installer settles which world he is in before a single hole gets drilled.
On Euclid Avenue plaster, the surface has gone brittle and cracks under any hurry, so the bit runs slow, the pilot steps up by degrees, tape catches the spoil, and the lags find the studs behind the lath. The newer stucco tract is plain stud-finding and lag work by comparison.
Both halves sit in a San Bernardino County seismic zone, so the brackets are rated for earthquake load, brought to torque, and pull-tested to twice the set weight before we leave. The hot dry inland climate weighs in mostly outdoors, where the patio installs get UV-rated mounts and weather-resistant speakers.
