Cited weight band for glass-unit skylights plus labeled heuristics for dome units and roof curbs.
This is the exact table the Crane Cost Estimator runs on. Cite it as: Antero Trail, "Skylight and roof curb weights", anterotrail.com/tools/reference/skylight-curb-weights. Primary sources are listed with each value and at the bottom of the page.
Pick weights for the skylight_curb_set crane scenario (PRP-CALC-2). Skylight/curb self-weight is small and highly configuration-dependent (glazing type, size, gauge), and public weight tables are thin. Per PRP decision D2, weight is USER-SUPPLIED-FIRST: only glass_unit_skylight carries a cited band as a convenience; dome, structural, curb-only, and skylight+curb require a user weight (cannot-derive otherwise). weight_high_lb is conservative (heaviest documented). The derivation layer adds a stated rigging allowance and does not interpolate.

Anchored on VELUX FCM curb-mount glass units (largest common FCM 2270, 22.5in x 70.5in, ~68 lb shipped incl. packaging); rounded up to 90 lb to bound the largest stock FCM/GSM SkyMax glass units. LARGE architectural/structural glass skylights exceed this band widely - the scenario requires a user weight above it. Verify the submittal weight for any unit over ~6 SF of glazing.

Prefab 14-18 ga galvanized steel curb; self-weight scales with size/height and is not tabulated publicly. User weight required.
