# 28" x 44" Inserts The **28" x 44" Inserts** collection features large, commercial-grade graphic tracking panels for high-visibility storefront promotion. These rigid marketing sheets slide easily into heavy-duty A-frame sidewalk stands and swinging curb signs. They fit cleanly along high-traffic convenience store perimeters, gas station approaches, and customer entryways. The professional panels ensure your active storefront appearance looks completely organized, helpful, and highly secure. Driving immediate point-of-purchase traffic safely requires placing clear, readable advertisements near primary pedestrian walkways. Station operators face major drops in foot traffic if specials are not clearly communicated to arriving guests. This specialized storefront layout completely eliminates missed sales opportunities by broadcasting active marketing messages beautifully. The sharp, high-contrast graphic alignments ensure that your pricing bursts, fresh food notices, or site directions remain perfectly stable. Sliding these heavy-duty printed media panels into your outdoor frames optimizes oncoming vehicle driver and pedestrian transit behaviors. It actively guides visiting motorists to purchase food combos, car wash bundles, coffee drinks, and seasonal merchandise items. This comprehensive lot messaging catalog demonstrates your dedication to establishing a structured, financially optimized consumer courtyard. We manufacture these resilient inserts utilizing high-impact .020 styrene and durable 4mm corrugated plastic (Coroplast). This tough material composition easily survives continuous blistering sun exposure, localized vehicle exhaust, and severe rain storms safely. The versatile configurations fit all standard 28" x 44" frame models and accommodate clear protective protective panels perfectly. Forecourt crews can slide, lock, or swap promotional graphics into position in just a few seconds. **These 28" x 44" signs are made to fit the following frames:** - WindMaster FP Curb Sign Frame **([U-WMFP](http://www.unitedsign.com/product-p/u-wmfp.htm))** 10mm Double-Sided Coroplast Insert - Wind Sign Deluxe Frame **([U-WSR-28](http://www.unitedsign.com/product-p/u-wsr-28.htm))** 4mm Single-Sided Coroplast Insert - United WindSign Snap Lock or Pole Mount Frame **([U-WS-14](https://unitedsign.com/products/aluminum-frame-pole-or-wall-mount-2))** .020 Single-Sided Styrene Insert - United WindSign Curb Frame **([U-WS-1](https://unitedsign.com/products/united-windsign-curb-frame-28-x-44))** .020 Single-Sided Styrene ## Products in this collection - [Clear Plastic Panel Insert - 28"w x 44"h](https://www.unitedsign.com/products/clear-plastic-panel) - 14.95 USD - [Ethanol Free Sold Here- 28" x 44" .020 Styrene Insert](https://www.unitedsign.com/products/ethanol-free-sold-here-28-x-44-020-styrene-insert) - 27.76 USD - [Car Wash Open- 28" x 44" .020 Styrene Insert](https://www.unitedsign.com/products/020-single-sided-car-wash-open) - 27.76 USD - [Closed for Maintenance- 28" x 44" Styrene Insert](https://www.unitedsign.com/products/020-single-sided-temporarily-closed-for-maintenance) - 27.76 USD - [Diesel Fuel Sold Here- 28" x 44" .020 Styrene Insert](https://www.unitedsign.com/products/diesel-fuel-sold-here-28-x-44-020-styrene-insert) - 27.76 USD - [DEF Sold Here Sign - Styrene Insert - 28" x 44"](https://www.unitedsign.com/products/def-sold-styrene-insert) - 27.76 USD - ["Wave Wash" Car Wash Menu Sign Insert (Custom Menu) - 28"w x 44"h](https://www.unitedsign.com/products/menu-insert-wave-wash) - 49.81 USD - [Car Wash Open/Closed Sign Insert - 28"w x 44"h](https://www.unitedsign.com/products/28-x-44-flip-panel-car-wash-open-closed) - 87.5 USD - [Breakfast Sammiches!
