Abstract
A hembar may define a front portion and a rear portion configured to slidably engage each other. The front portion and the rear portion, when slidably engaged, may define a slot configured to receive a piece of fabric. The front portion and the rear portion may be configured to clamp the piece of fabric within the slot. The front portion and the rear portion may be configured such that a width of the slot is adjustable. The front portion may define a first attachment surface and the rear portion may define a second attachment surface. The first attachment surface may define a rib. The second attachment surface may define a groove configured to receive the rib when the front portion is slidably engaged with the rear portion such that the piece of fabric is clamped within the slot.
