Gillinder Brothers Inc.

Gillinder Brothers Inc., doing business as Gillinder Glass, manufactures optical components and lighting products for defense logistics and aviation supply chains as a small-business prime contractor operating exclusively on full-and-open federal awards. The Port Jervis, New York–based manufacturer holds 199 prime awards spanning forty-six years, with recent work concentrated on airport marker light filters, electric lighting globes, and optical lenses for the Defense Logistics Agency Aviation. The company operates as a for-profit manufacturer and has been registered in the System for Award Management since 2002; it competes predominantly under Total Small Business set-asides for roughly 20% of awards and full-and-open competitive procurement for the remainder.

Gillinder Glass's customer base is monolithic — the Defense Logistics Agency accounts for 156 of the 199 awards in the portfolio. DLA Aviation alone anchors 90 awards valued at $1.6 million in combined potential value and represents 84% of award volume across the top customer set. The remaining DLA components (Troop Support Construction and Equipment, Land and Maritime, and the parent agency) and the Department of the Navy account for the rest; no other federal agency has placed more than a handful of orders. This concentration reflects Gillinder Glass's position as a specialized optical-components supplier embedded in DLA Aviation's just-in-time supply chain for military aviation equipment.

Gillinder Glass holds five active Indefinite Delivery Contracts with DLA Aviation, with individual ceiling values of $250,000. The highest-activity vehicles are IDC SPE4A620D5606 (10 task orders, $23 thousand combined potential value), IDC SPE4A614D5AAD (9 task orders, $11 thousand combined potential value), and IDC SPE4A615D5478 (7 task orders, $9 thousand combined potential value). Work performed under these vehicles consists of delivery orders for specific optical components — filters, lenses, globes, and marker lights — tied to NSN-driven military aviation component codes. Representative recent awards include a $27,348 Total Small Business purchase order for airport marker light filters (January 2026), an $11,572 Total Small Business purchase order for electric lighting globes (October 2025), and a $5,283 full-and-open purchase order for light lenses (February 2025), all for DLA Aviation.

Award activity is sporadic and declining. The vendor received 3 awards in 2022, 6 in 2023, 1 in 2024, 3 in 2025, and 1 in the first month of 2026. Combined potential value across all 199 awards totals $2.1 million, with combined dollars obligated at $3.1 million (151% of potential value), indicating that invoiced value has exceeded ceiling prices. The company has no subcontract footprint; all awards are prime contracts or task orders under its own IDCs. Gillinder Glass's capability portfolio is narrow — 139 of the 199 awards fall under PSC code for indoor and outdoor electric lighting fixtures, and 53 under electric vehicular lights and fixtures — making it a purpose-built supplier to DLA Aviation's optical-component logistics mission rather than a diversified defense contractor.
