One of our customers complained that he was constantly breaking the plastic flashtube covers on his Balcar heads, and spending a small fortune to replace them. To help him out, we came up with this far more durable metal cap. He hasn't had to replace a cover since.
If your original Balcar covers need replacing, here's a heavy-duty alternative to those plastic caps. Made of stainless steel, and fits virtually all standard Balcar flash heads with two or three mounting tabs.
