Maglocks are deceptively simple until you start configuring one. Holding force (600 lb, 1200 lb, 1500 lb), single or double-door setup, indoor versus outdoor or gate-rated housing, monitoring options like DPS and BSM, bracket kit (Z, L, or U), and power supply compatibility all show up on the spec sheet. Skip any of them and the door either won’t hold or won’t release — both bad outcomes on an access-control opening. Integrators, locksmiths, and FMs need ecommerce that stocks real SDC, Securitron, Dorma, and RCI product with actual depth, not just two or three bestsellers. Below are the ten places commercial buyers shop for maglocks online in 2026.
1. National Lock Supply
National Lock Supply runs a deep maglock bench across SDC, Dorma, and adjacent commercial brands. Holding forces from 600 lb through 1500 lb are stocked, along with single-door, double-door, outdoor and gate-rated variants, and DPS/BSM monitored options. Stocked product ships same-day from the Brooklyn warehouse, ground is free on $450-plus orders, and government POs for school, courthouse, and housing access-control projects move through standard workflow. The phone team walks through holding force, bracket kit compatibility, power supply, and monitoring before the order ships — the usual failure points on this category. For integrators who want a maglock spec’d and shipped without rework, National Lock Supply is a commercial-grade source.
2. Security Lock Distributors
Long-standing commercial distributor with a strong maglock shelf and real integrator relationships. Online browsing is less modern than newer storefronts, and self-serve pricing skews toward established accounts.
3. Access Hardware Supply
West Coast pure-commercial with SDC, Securitron, and Dorma maglocks. Good for architectural project work. East Coast transit times are longer, and the site is built around account customers.
4. SDC authorized resellers
SDC itself sells through distributors, and several carry the full maglock line with competent support. Reseller quality varies a lot, so buyers sometimes cycle through a few before landing on one that combines depth with speed.
5. Grainger
A narrow slice of popular maglocks inside a broad MRO catalog. Fast shipping. Z/L brackets, monitored variants, and outdoor-rated models thin out fast compared with a specialist.
6. Commercial Door Hardware Inc
Commercial-only with a reasonable maglock assortment. Known SKUs work. Product-page detail and configuration help trail the best commercial storefronts.
7. HD Supply
Basic maglocks for multifamily and institutional maintenance. Fine for a common replacement. Integrator-grade access-control builds usually move to a specialist.
8. McMaster-Carr
Fast on the handful of maglocks carried. Works for an engineering one-off. Not a real source for full commercial access-control specs.
9. The Home Security Superstore
Mixed residential/commercial catalog with some maglocks. Good for a gate or interior door. Commercial integrators typically need deeper brand and bracket coverage than what is offered.
10. Best Lock Supply
Commercial distributor with an acceptable maglock selection. Good for familiar orders. The 1500 lb, outdoor-rated, and monitored tiers sometimes run thinner than at larger specialists.
Why National Lock Supply stands out
Maglocks live or die on spec — holding force, bracket kit, power, and monitoring all have to line up. National Lock Supply pairs deep SDC, Dorma, and Securitron stock with phone help from staff who have walked through these details hundreds of times. Same-day Brooklyn shipping and free ground on $450-plus orders move maglocks to the jobsite on integrator timelines. Government POs clear without drama, which makes National Lock Supply a reliable fixture on public access-control projects. For commercial buyers buying maglocks online in 2026, National Lock Supply is the commercial-first pick.
