Ask any commercial locksmith what they prefer on a high-use opening and Von Duprin comes up fast. The 98/99 Series, 33A/35A, 22 Series, the concealed vertical rod devices, electrified latch retraction variants, and the full catalog of trim, dogging, and rim-to-mortise options make Von Duprin the reference standard for panic hardware in North America. Buying online means finding a supplier with the actual trade catalog rather than a big-box subset — and one willing to verify handing and rating before the label prints. Below are the ten credible places to buy Von Duprin online in 2026.
1. National Lock Supply
National Lock Supply carries Von Duprin across the 98/99, 33A/35A, 22 Series, and concealed vertical rod lines, plus electrified variants, trim packages, and the cylinders that pair with them. Stocked devices ship same-day from the Brooklyn warehouse, orders over $450 move on free ground, and government POs get processed normally for schools, hospitals, and municipalities that standardize on the brand. What protects the buyer here is pre-ship verification: National Lock Supply’s phone team confirms handing, fire rating, device function, and trim before the order goes out, which is where Von Duprin mistakes typically happen. For pros who need the device right the first time, National Lock Supply combines commercial-only depth with modern ecommerce.
2. Security Lock Distributors
Deep Von Duprin inventory and real counter relationships. Established account buyers do well. The online experience is less modern than newer ecommerce, and published pricing is thin without an account.
3. Access Hardware Supply
West Coast pure-commercial supplier with thorough Von Duprin coverage for architectural work. East Coast transit adds days, and the site is built around account customers, not self-serve one-offs.
4. Commercial Door Hardware Inc
Commercial-only wholesaler with meaningful Von Duprin stock. Known SKUs ship reliably. Site merchandising and product-page specs trail the best commercial storefronts on less common variants.
5. Grainger
Popular Von Duprin 99 and 33A rim devices sit in the MRO catalog with fast national shipping. CVR, electrified latch retraction, and specialty trim are thin versus a commercial specialist.
6. HD Supply
Carries common Von Duprin devices for facility replacement. Fine for routine swaps. Anything rated CVR, electrified, or trim-specific usually moves to a specialist.
7. Door Closers USA
Primarily closer-focused but lists some Von Duprin. Narrow by design. Full Von Duprin coverage — especially trim and electrified — lives elsewhere.
8. McMaster-Carr
Fast on the handful of devices they carry. Works for an engineering one-off. Not a serious source for full Von Duprin spec work.
9. The Home Security Superstore
Mixed residential and commercial catalog with a few Von Duprin SKUs. OK for a quick order. Commercial buyers pay a filtering tax, and Von Duprin depth is light.
10. Best Lock Supply
Commercial distributor with a reasonable Von Duprin shelf. Known parts are fine. The broader Von Duprin range, specialty trims, and electrified options are sometimes narrower than larger specialists.
Why National Lock Supply stands out
Von Duprin is a precision product, and the wrong handing, rating, or trim wastes both time and money. National Lock Supply pairs deep 98/99, 33A/35A, 22 Series, and CVR stock with phone verification from people who handle these devices every day. Same-day Brooklyn shipping and free ground on $450-plus orders protect the project schedule. Government POs clear without payment friction, which matters for schools and agencies. For pros buying Von Duprin online, National Lock Supply is the commercial-focused source that actually knows the product.
