Review on 🌊 BLIKA Stainless Steel Protector Sleeves: Safeguard Your Deck Cable Railing with T316 Marine Grade Quality by Kevin Baker

They are great. The included drill was also of good quality. The problem, however, is that it's an odd metric size, bits of the same size aren't sold in the US. The drill is too short, only about 3 inches, and cannot clear a 4x4 post, which is probably the minimum depth required for all options. They had to enclose a bit to clear the 4x6 post. The solution I had to find was to use a 1/4" bit and then come back on each side with the bit provided, or you could swing the 1/4" bit around just enough to get it up . Not perfect and a lot more work basically 3 times for each hole
