	Aluminum Servo Side-Mount Bracket This bracket is part of the Low Profile Axis. However, we're offering it separately to be used to mount a servo to anything with the Servo Erector Set hole pattern. Design to be used with the plastic low profile gear set.	ASB-14	RB-Lyn-154
	Aluminum Dual Inline Multi-Purpose Servo Bracket Rev2 High quality aluminum servo bracket, available in black anodized finish. Works great for making multi-axis joints for use in robot arms and legs. Fits standard size Hitec servos.	ASB-15	RB-Lyn-330
	Aluminum Servo Offset Axis Bracket High quality aluminum servo bracket, available in black anodized finish. Works great for making a wrist rotate for a robotic arm, or as a bicep rotation on a humanoid arm. Fits standard size servos.	ASB-16	RB-Lyn-177
	Aluminum 15 Degree Ankle Bracket High quality black anodized aluminum 15-degree ankle servo bracket. Used in the reverse knee biped legs for the ankle joint. Designed for use with ARF-02, but can work with ARF-01 as well. Sold in a 2-pack. Fits standard size servos.	ASB-17	RB-Lyn-357
	Aluminum Mechanical Advantage Bracket High quality aluminum servo bracket, available in black anodized finish. Perfect for making an indirect drive axis using the Ball Bearing Hub and other components. Fits standard size servos.	ASB-21	RB-Lyn-390
	Aluminum Multi-Purpose Rotate Servo High quality aluminum servo bracket, available in black anodized finish. These brackets are similar to the ASB-04 except they have the SES hole pattern on the opposite side of the servo output shaft. This makes it possible to to make a rotation that is in line with the servo. Works great for making multi-axis joints for use in robot arms and legs. Fits Hitec standard size servos.	ASB-24	RB-Lyn-535
	Aluminum Inline Multi-Purpose Rotate Servo Bracket High quality aluminum servo bracket, available in black anodized finish. These brackets are similar to the ASB-04 except they have the SES hole pattern on the opposite side of the servo output shaft. The "inline" means that the SES patterns on the bottom and side of the bracket are in line with the servo shaft. Works great for making multi-axis joints for use in robot arms and legs. Fits standard sized Hitec servos.	ASBI-24	RB-Lyn-345
SES - LSS Brackets
