Most keeps are adjustable by a small amount, often by an eccentric cam or a slotted fixing. Balancing them so no single point over-compresses while another sits slack is a fifteen-minute job that transforms how a stiff, leaky opening behaves.
Over-tightening is the common mistake. Excess compression crushes the seal permanently, raises handle effort and accelerates wear in the gearing, which is why adjustment is done in small increments and tested each time.
