Morphology

trimmer + arch

The meaning is directly compositional: combining 'trimmer' (a framing joist that supports an opening) with 'arch' (an arched load-bearing structure) yields an arch placed between trimmers to support a hearth or fireplace opening. Although the term is technical, the noun+noun composition follows regular English compounding patterns, so a learner who knows both constituents can infer the MWE's meaning.

Etymology

The noun trimmer arch is a small arch built between two short floor beams called trimmers so a heavy fireplace can sit safely on the floor. The arch passes the weight to the nearby beams, which is why the name means 'an arch between trimmers'.
