As part of the support package, the winning clubs aim to develop their underage structure, introduce outdoor exercise stations, refurbish changing rooms, and improve showering facilities.
The four winning clubs have been awarded with €5,000 of goods and resources to use during their planned Ulster Bank RugbyForce weekend. The first 50 clubs who registered for the initiative will also receive smaller packs, worth €250.
Speaking at the announcement of the Ulster Bank RugbyForce winners; former Ireland and Munster player Alan Quinlan said: "Ulster Bank RugbyForce is a great initiative which aims to support the grassroots of Irish rugby. Rugby clubs across the country need the backing of their fans and their community. New generations are being brought up on provincial rugby but, it is so important to remember that you don't need to travel to Limerick, Dublin, Galway or Belfast to see a great game."
Ten other clubs from Ulster will receive support packages to the value of €250:
Armagh, Banbridge, Belfast Harlequins, Larne, Letterkenny, Lisburn, Londonderry YMCA, Portadown, Randalstown, Tir Chonaill, Lurgan.
