Mapping the Morris Number Ranges to the Job
Morris organizes its catalog by five-digit number blocks, and once the blocks are known the whole 1,760-item collection can be searched by range instead of scrolled. The families below follow those blocks in order, from the conduit run to the final termination.
Which Morris Family You Need
Conduit Bodies and Rigid Fittings, the 14000s
The run starts with LB, T, LR, LL, and C conduit bodies in aluminum, threaded rigid, EMT set screw, and combination versions from 1/2 inch through 4 inch. Mogul bodies with cover and gasket follow, plus couplings, box connectors, nipples, and bushings including grounding types with lugs. A condulet, the trade name for a conduit body, is picked by its letter shape, and the letter is in every title.
EMT, Liquid Tight, and Service Entrance, the 15000s
Set screw and compression EMT connectors and couplings run through 4 inch with rain tight and insulated throat versions, alongside straight, 45 degree, and 90 degree liquid tight connectors. Squeeze connectors for flexible conduit, Kenny clamps, cord grips, and aluminum service entrance caps in clamp-on, threaded, and mast slip fitter styles complete the block. The 16000s add EMT and galvanized rigid elbows, the 17000s strut bases and beam clamps, and the 19000s pipe straps.
Locking and Straight Blade Devices, the 20000s and 89000s
The device blocks carry NEMA locking plugs, connectors, and receptacles from L5-15 through L16-30, including 277V and 480V patterns and recessed versions, plus hospital grade and standard straight blade devices, dryer and range receptacles, appliance cords, and power strips. The wired families file in the site's receptacle collection where they overlap it.
Boxes, Covers, and Weatherproof Hardware, the 36000s through 38000s
Weatherproof boxes run one and two gang, standard and deep, in gray, white, and bronze with three to nine threaded outlet holes, matched by flat covers for duplex, GFCI, and twist-lock devices and by metal while-in-use covers. The 84000 block adds recessed floor box assemblies and recessed receptacle plates, which cross-file in the floor box collection.
Switches, Sensors, and Dimmers, the 70000s through 83000s
The 70000 block is appliance and equipment switching, heavy duty toggles to 4PDT, rockers, push buttons, and door switches, while the 80000s add in-wall digital and astronomic timers plus PIR wall, ceiling, and high bay sensors that file in the occupancy sensor collection. The 82000s carry LED dimmers in 120V, 0-10V, and 12V or 24V DC formats, and the 83000s stainless steel wall plates.
Lugs, Grounding, and Insulated Connectors, the 90000s
The termination half of the catalog is its deepest: split bolts, mechanical and compression lugs in copper and aluminum through 1000 MCM, and panelboard and meter socket lugs. Neutral and ground bars, C-taps, irreversible grounding connectors, and a full ground clamp program for pipe, rebar, I-beam, and rod carry the grounding side. The 97000 block closes with black and clear insulated multi-port connectors from 2 to 12 ports, and the tools to land it all sit in the 50000s.
Reading a Morris Part Number
The five-digit number places the item in its block, and the title carries the spec in plain text, material, family, style, then size, so 14304 reads as a 14000-block aluminum mogul conduit body at 3 inch. Lettered SKUs are the exception: the PVC conduit bodies use shape and size in the code itself, LB200CBPK being the 2 inch LB body, with six sizes in each of the five shapes. A B at the end of a lug number, as in 90734B, marks the bulk pack version of the same lug, which the title states outright.
Ordering Notes for Morris Hardware
Order fittings by trade size exactly as titled, since 1-1/4 inch and 1-1/2 inch bodies look identical in photos and do not interchange. On lugs, match the conductor range and the stud size, both stated in the title, and note that one-hole and two-hole pads of the same wire size are separate numbers. Insulated multi-port connectors are picked by wire size and port count together, and the bulk-pack B suffix changes the quantity you receive, so check it before comparing prices.
Specs to Confirm Before a Morris Order
Confirm the conduit system first, rigid, EMT, or liquid tight, because connector families do not cross over, then the trade size and whether an insulated throat is required. On grounding, match the clamp to the pipe or rod diameter and the conductor range, and on lugs confirm copper against dual-rated aluminum for the conductor in hand. On devices, verify the NEMA pattern and voltage, especially in the 277V and 480V locking range. Certification listings vary across this many product classes, so read them on the item page.
Where Morris Sits in the Lumera Catalog
Device-side placements are the strongest, led by 51 Morris toggle and rocker units in the switch collection.
The 82000 block puts 22 models in the dimmer collection, covering the 120V, 0-10V, and DC formats.
The stainless program adds 13 plates to the wall plate collection. The fitting, lug, and grounding majority of the catalog has no matching category tree on the site yet, so those items are reachable only from this brand page and search, and the wiring device category currently holds just 4 Morris entries.
Morris Fitting and Lug Questions
What do LB, LR, LL, T, and C mean on a conduit body?
They are the standard shapes: LB turns the run 90 degrees with the cover on the back, LR and LL turn right or left with the cover on the side, T splits the run three ways, and C runs straight through for pulling access. Morris states the shape letter and size in every title, so the search box finds a 2 inch LB directly.
Is there a difference between the set screw and compression EMT fittings?
Both join EMT, but set screw fittings fasten with screws for dry interior work while compression fittings clamp a gland ring and are the usual pick where a snug, neater termination is wanted, with rain tight compression versions for wet locations. The catalog carries both in the same size range, so the choice follows the location and specification.
Which Morris lug fits 500 MCM cable?
Several families do, and the choice is copper against aluminum body, short against long barrel, one against two mounting holes, and the stud size, all of which appear in the title. Filter the search to 500 MCM, then match the stud diameter of the equipment pad before ordering.
Are the insulated multi-port connectors sized by wire or by ports?
Both: each connector is rated for a maximum conductor size and built with a fixed port count, from 2-port splices to 12-port distribution blocks in black or clear housings. Pick the wire size first, then the number of conductors landing in the block, and the matching number follows.
