Tower Products Incorporated

Tower Products Incorporated, operating as Markertek Video Supply Division and doing business as Markertek, is a for-profit Subchapter S corporation based in Saugerties, New York that supplies commercial off-the-shelf audio, video, and broadcast equipment to federal agencies as a prime contractor (97% of recent awards), competing predominantly on full-and-open ground without set-aside posture on its core GSA Multiple Award Schedule work, though accepting Total Small Business set-asides when offered on direct DLA and FAA procurements.

Markertek's capability portfolio centers on broadcast-grade audio and video equipment, interconnect solutions, and communications systems. Representative prime work includes a $153,908.96 Total Small Business delivery order from the Air Force (September 2025) for wireless equipment supporting the USAF Band under GSA MAS, a $91,550.77 Naval Sea Systems Command purchase order (September 2024) for Barnfind Technologies video transceiver equipment (BNC transceivers, CWDM transceiver modules, and fiber optic converters), a $79,317.26 Secret Service delivery order (August 2024) for BlackMagic Cloud products, and a $88,239.80 Voice of America purchase order (September 2022) for a Phabrix analyzer and mount kit. Markertek also supplies smaller discrete items—cables, connectors, modulators, microphones, and test equipment—in the sub-$5,000 range across Navy, GSA, FAA, and Army customers. The company maintains a GSA Multiple Award Schedule contract valued above $7.5 million, anchoring most transactional volume.

Customer concentration skews heavily toward GSA Federal Acquisition Service by dollars (20 awards, $19.6 million combined potential value, 89% of top-customer coverage) due to the schedule vehicle's leverage across all federal agencies, but by award count the Naval Sea Systems Command dominates (53 awards, $400 thousand combined potential value), followed by the Department of the Army (50 awards), Defense Media Activity (37 awards), the Marine Corps (26 awards), and Voice of America (22 awards). This split reflects Markertek's dual posture: high-value periodic equipment sales under GSA MAS to civilian and defense agencies alongside high-frequency, low-value consumables and component orders from Navy technical commands.

Markertek's primary vehicle footprint sits on the GSA Federal Supply Schedule GS03F0035R (248 task orders, $1.1 million combined potential value) and the Multiple Award Schedule (54 task orders, $520 thousand combined potential value), both of which enable rapid quote-and-delivery to any federal customer. The vendor also sits on the Advanced Technology Support Program IV and Responsive Strategic Sourcing for Services contracts at lower transaction volumes.

Activity has remained stable year over year—approximately 19 to 22 awards annually from 2022 through 2025—with 621 total awards in the source data spanning back to November 2001. The 23% obligated-to-potential ratio reflects the highly transactional, equipment-supply character of the business: agencies place orders, Markertek delivers hardware quickly, and contracts complete. No significant recompete cliff appears in the awards; most work renews through standing GSA vehicle task orders.

In its minor subcontractor role (3% of awards), Markertek supplies specialized audio, video, and cable equipment to defense systems integrators. Named primes include General Dynamics Information Technology, BAE Systems Technology Solutions & Services, General Dynamics Global Force, L3Harris Integrated Systems, Lockheed Martin, Northrop Grumman Systems, Science Applications International Corporation, and KBR Wyle Services. Recent sub work includes IP transceiver belt packs and headsets to NASA JSC (March 2026) under General Atomics, video processing equipment under KBR for a Mission Systems Operations Contract (November 2025), and wireless intercom digital beltpacks and related Freespeak equipment to BAE on Navy SCMS contracts (February–March 2025).

NAICS concentration runs across 309 awards in Other Communications Equipment Manufacturing, 76 awards in Audio and Video Equipment Manufacturing, and 55 awards in Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing; PSC concentration is dominated by Radio and Television Communication Equipment (211 awards). Markertek registered in SAM in December 2001 and operates exclusively through direct equipment sales and supply, avoiding systems integration, labor, or service-heavy engagements.
